Protocols

2009-12-14T02:35:00.001-08:00

Protocols are set of rules and procedures for communicating. There are many protocols are used but some are commonly used protocols. They are:
TCP/IP
NetBEUI
DECnet
X.25
IPX/SPX and
AppleTalk
But the most important protocol is TCP/IP. In this protocol data transmission is managed by dividing the data into different pieces called packets. Each packet of data contains a part of actual data, source computer address, destination address, and information for reassembling data at destination computer. These packets of data travel along the fastest available path in the network. This type of data transmission is called packet switching and is used in internet communication. This is the reason that the protocol is also called Internet Protocol.
TCP/IP is divided into 3 usable classes and 2 experimental classes. Class A, B, C are usable classes and D, E are experimental classes. We can not use experimental classes in network.
Classes Range
A 1.X.X.X 126.X.X.X
B 128.X.X.X 191.X.X.X
C 192.X.X.X 223.X.X.X
D 224.X.X.X 239.X.X.X
E 240.X.X.X 254.X.X.X
127.X.X.X is used for troubleshootin

Selecting a Scanner

2009-10-16T05:13:00.000-07:00

Types of Scanners

Scanners come in a variety of configurations. The type you should consider depends on both your planned scanning needs and your budget.

* Drum scanners. This type of scanner provides the highest level of image quality. They are typically found at professional printing businesses. In a drum scanner, the original is attached to a cylindrical drum and rotated past the sensing elements. These scanners are very expensive, with capabilities that go well beyond the needs of desktop scanning.

* Flatbed scanners. This type of scanner provides a flat glass surface onto which the original is placed. The illumination and sensing elements move under the glass to scan the image. Flatbed scanners are available in a wide range of sizes, prices, and capabilities. Some flatbeds offer a transparency scanning adapter as an option.

* Single sheet scanners. This type of scanner is designed for single sheets of paper. You insert one edge of the paper in a slot and the scanner grabs it, feeds it past the sensing array, and passes it out the other side. Some single sheet scanners are even integrated into keyboards. Such scanners were originally designed for digitizing documents and images for archiving, and many models are not suitable for creating high-quality images.

* Sheet-fed scanners. These scanners take a stack of pages and scan them in sequence while you get coffee. Some even do duplex (2 sided) scans. They are very useful in some situations but not much use to the philatelist.

* Photo scanners. This type of scanner is designed to scan snapshots up to approximately 4´6 inches in size. Some are separate desktop units; others install directly into a computer much like a diskette drive.

* Hand scanners. This type of scanner requires the user to manually scan an image. Hand scanners look something like an overgrown mouse. To scan, you manually drag the unit over the original document. Handheld scanners are suitable only for small originals that are no wider than the scanner itself. In theory, most hand scanners permit you to scan a wide original in two or more passes and "stitch" the scans together into a final image. This, however, never works as well as the manufacturers claim.

* Slide scanners. This type of scanner is designed for scanning slides (transparencies) rather than opaque originals, such as photographic prints. While rarely relevant for scanning philatelic material, a dedicated slide scanner is the best choice for scanning slides. Some flatbed scanners come with transparency adapters but they do not provide top quality results, particularly with small slides such as 35mm. Slide scanners have very high resolution, typically a minimum of 2400 dpi, required for getting all the details out of your slides. Many slide scanners also have the ability to scan color negatives and to convert the negative image to a positive image.

For philatelic purposes, a flatbed scanner is undoubtedly the most versatile. You can scan anything from a single stamp to an entire stock book or album page. A hand scanner may be a viable alternative, particularly if your budget is tight. Their width limitation does not matter so much for stamps and covers. I have also seen single sheet scanners and photo scanners used successfully for philatelic purposes, although they require that the item being scanned be sandwiched between clear plastic sheets for feeding into the scanner.

Stop XP Pop-ups

2009-10-14T03:58:00.000-07:00

First off, never trust a company that exploits a technology to advertise that they can prevent it. Second, yes you can stop these. You are probably familiar with Windows (a/k/a MSN) Messenger which is used for Instant Messaging. There is another program called Messenger that is used in networks to transmit and send Alerter service messages between clients and servers.
Even though you'll never use it, unless you are on a network, by default it is turned on, causing an open hole in your XP firewall for pop-up advertising to get through. Here's what to do if you want to stop Messenger...
Go to Control Panel / Administrative Tools / Services (or Start / Run and type in " services.msc "). This will bring up a long list of Windows services that are running or available on your system.
Find "Messenger" and double click to open the Properties box. In the "Startup Type" field, change the setting to "Disable". If any services depend on Messenger and fail to start, then change to "manual".
Click OK to save changes.

IP Addressing

2009-10-13T08:43:00.000-07:00

IP stands for internet protocol. Basically it is a unique identifier for a computer on the internet. It is numerical address with four numbers separated with dots and the format of an IP address is a 32-bit.Each number can be start from 0 and ends with 255. For example IP address looks like this: 131.200.1.1

Every computer on the internet using unique IP address and this IP address can be static and dynamic. A server has a static IP address that does not change. When a computer dialing internet through modem then that computer has a IP address that is assigned by the local ISP. Your local ISP assigned you unique IP address for each session and it may be different each time.

You can connect to any server using this IP address. if you simply type http://131.200.1.1 and arrive at the machine that contains the Web Server for the specified IP address.

TCP/IP is divided into 3 usable classes and 2 experimental classes. Class A, B, C are usable classes and D, E are experimental classes. We can not use experimental classes in network.

Classes Range

A 1.X.X.X 126.X.X.X

B 128.X.X.X 191.X.X.X

C 192.X.X.X 223.X.X.X

D 224.X.X.X 239.X.X.X

E 240.X.X.X 254.X.X.X

127.X.X.X is used for troubleshooting.

What is Internet Fax?

2009-10-06T08:51:00.000-07:00

Internet fax is a type of online service that provides subscribers with the ability to send and receive faxes without a fax machine. Instead, Internet access and an email account is all that is required.
To use an Internet fax service, a subscriber signs up for a small monthly fee and is assigned a fax number. When a fax is sent to the subscriber's number, the service accepts the fax, turning it into a file that is forwarded to the subscriber's existing email address.
To send an Internet fax, the subscriber creates an email. The fax content can be written in the body of the email, and attachments are normally permitted. The destination fax number is entered in the "To" field, along with "@" and the Internet fax service name. For example, if the fax number were 1-550-234-5678, the email would be addressed to 15502345678@site.com. In the "Subject" field the user enters the name of the recipient, "Attn: Mr. Jam" for example.

A small toolbar, available for download from the Internet fax service, is used as a plug-in inside the email program. Clicking on the "Send" button on the toolbar sends the email to the Internet fax service. Upon receipt, an automated program converts the email to a fax format, then faxes to the number supplied in the "To" header. The recipient receives the fax normally, through his or her fax machine.
This service can be very convenient. Of the many advantages, your assigned fax number is active 24 hours a day, so that your account can accept faxes around the clock. Contrast this with using a fax machine, which relies on your phone system being free to accept a fax. For those that use one phone line for fax, telephone, and dial-up, an Internet fax service is especially handy. Internet fax services also save paper and fax toner, and do not rely on a serviceable fax machine. All faxes are sent and received as files. They can be printed by choice, but it isn't necessary.
A further advantage of an Internet fax service is that the subscriber does not need to be familiar with faxing software or fax machines. The convenience of sending and receiving faxes by using the familiar email interface appeals many people.
One of the best features of Internet fax services is that many offer toll-free fax numbers for the U.S. and Canada, so that your U.S. and Canadian clients can fax you for free. Sending faxes is also free of phone charges for the subscriber, as he or she is only sending emails.
When looking into Internet fax services, consider a service that offers a secure website. This provides a mobile "portal" to send/receive faxes while you're on the road or away from home. Confirmation of sent faxes should be standard, so you can be sure your client got your communication. The ability to send to more than one fax number at a time can also be valuable. Check for a page capacity, as some services may limit the amount of pages the subscriber can send/receive in a month.

General Packet Radio Service (GPRS)

2009-10-03T04:02:00.000-07:00

GPRS protocol is a packet-switch protocol; define for web applications in GSM network. In other words Internet on GSM network is standardized as GPRS network. GPRS has digital structure and this structure based on Time Division Multiple Access (TDMA) technique. One TDMA frame has 8 time slots (TSs). These TSs can be allocated to users, and single TS can be shared by several active users for uplink and downlink purposes. Different coding schemes are used to enhance data rate from 9Kbps to 150 Kbps per user, and it takes 0.5 to 1 second. Security features in GPRS is provided by GSM network.

GPRS Architecture

Global System for Mobile Communication (GSM) circuit-switch architecture does not support the GPRS packet-switch architecture. Thus, GPRS requires its own network architecture. Several networks and databases e.g. Mobile Station (MS), Base Station Subsystem (BSS), Home Location Register (HLR), Visitor Location Register (VLR) in existing GSM network are modified in GPRS network.

GPRS architecture introduces the following network nodes to GSM architecture.

Serving GPRS Support Node (SGSN)

Gateway GPRS Support Node (GGSN)

Mobile Station (MS)

Base Station System (BSS)

Home Location Register (HLR)

Visitor Location Register (VLR)

What is ADSL?

2009-10-02T03:21:00.000-07:00

ADSL stand for asymmetric digital subscriber line, here asymmetric means data speed does not same in both directions (upload and download) and provides high speed on already exiting telephone lines and same time you can use internet and as well as your line for phone. It is faster than DSL and but ADSL downstream speed (downstream rate ) is different with upstream speed (sending rate ). ADSL is much easier to install and provides much faster data transfer rate. ADSL support data upstream rate is 16 Kbps to 640 Kbps and data downstream rate is 1.5 to 9 Mbps. Normally ADSL and download and upload speed is averagely 10 time more than a normal dial up connection.
Your DSL connection to the Internet will always on, there is not need to dial your ISP each time to use internet and the main requirement for ADSL connection is modem. There are many option in modem hardware for example: USB ADSL Modem, PCI ADSL Modem, and ADSL Router, but mostly used USB Modem because easy to install. For 1 or 2 computer the USB modem is best but for more than 3 computer you should use Ethernet ADSL modem. ADSL connections are more useful in applications like videoconferencing, to run online movies and upload and download heavy files. This connection is ideal for today business requirements.

Hidden User Account

2009-09-19T04:03:00.000-07:00

For my next trick I will make a user account disappear, yet remain a full functioning account. Today's Security Tip is another way to lock down your system, and it does this by hiding specified user accounts. This feature is only available in XP and 2000, so unfortunately the rest of you are out of luck. This process does involve an easy registry edit, but if you're uncomfortable with that you might want to think twice about attempting this.

Normally when you log into XP, you see the startup screen where you see all the icons for the users who can access. What this tip does is allow you to hide a desired account from this screen. If you want to log on as this user you have to press Cntrl+Alt+Del twice at the Welcome screen to make a Windows Security dialog box appear. Here you can type in the user name and password of the hidden account and log in. Limited Users shouldn't be able to see any sign of you except for the listing in the Documents and Settings folder. Other administrative users will be able to see your hidden account in Control Panel/User Accounts, so keep this in mind when you're planning this out.
All right, now down to the good stuff. If having a hidden account sounds like your cup of tea, and you have no problem with small Registry augmentation, then let's go:
* First we need to open up the Registry Editor. Go to Start/Run and type "regedit" and click OK
* You should be looking at the Registry editor, and what we need to do now is navigate to H-KEY\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\Userlist . You will not see this folder if you do not have "show hidden system files" turned on.
* Once here we need to create another DWORD value. This is easier than it sounds, right click on the User list label file on the left side of the screen and select New>DWORD . You'll see the new entry in the right pane of the window, rename this value the name of the user account you want hidden (exactly how it is listed in the Startup screen, case sensitive) and leave the value at 0.
* Close your Registry Editor and restart the PC. When the Welcome screen comes up you'll notice that there's no icon for the user you just concealed. So how do you log in? This is where you press Cntrl+Alt+Del 2x's and the Windows Security Dialog box will come asking you to authenticate (name/password) after this the system should log you in.
Here's one more thing you might want to keep in mind, Windows logon screen. This is the screen where you see the available users you can choose to log in as. You can turn this option on/off in the User Accounts ( Start/Control Panel/User Accounts then "Change the way Users log in or off" and "Use Windows Welcome Screen" and you need to turn it off if you plan on using a hidden account and there are no other accounts on the system. The reason why is that the Windows doesn't have any user accounts to display in the Welcome screen, so it will continuously reboot. Now if you do run into this or any problems simply enter Safe mode at the next boot, this will allow you to go to the User Accounts Window and fix any problems. If you find that you can't log in at all with your hidden account go back and look at the registry value you created. Make sure you're spelling the user name is correct and that it's in the right location in the registry.

Forbidden file and folder names in windows 2000 and XP

2009-09-18T05:58:00.001-07:00

Today an interesting tip about some names which windows has reserved. You can say there are some restricted words that cannot be assigned to name of files and folders. If you create a folder on your desktop and try to rename it with name “con” (or others reserved words) then the message will be appear in windows 2000 “Cannot rename New Folder: A file with the name you specified already exists. Specify a different filename” or “Cannot create or replace file: The filename you specified is invalid or too long. Specify a different filename”.
In windows XP when you try to rename a folder with reserved word then it automatically reverts the folder back to its original name.

You can give surprise to your friends with this interesting tip and show them this trick with that restricted words
The following are reserved names, which cannot be assigned to a folder or file (normally):
CON
PRN

AUX
NUL
COM1
COM2

How Firewalls Work

2009-09-17T06:39:00.000-07:00

There are mean people out there that want very badly to get into your system or network. Maybe they want to steal information, to simply cause as much destruction as possible, or to use your system for their own uses. If you're online a lot or have a broadband connection, the attempts to enter your system may be relentless.
I feel that there are three main areas of defense against these threats: Anti-virus (of course), Firewall, and Spyware removal. With some programs being more important than others, but none being without importance. What I would like to do is give all of our readers at least a good concept of what these Firewalls and Anti-virus programs do to protect your system. I'm going to attempt to highlight the functions of these utilities and even some good practices that you can implement.
This week I'll be discussing the first line of defense between you and the Internet firewall. A firewall isn't going to stop you from getting a lot of viruses out there, unless it's the kind of viruses that proactively scans systems for open ports like the 32.Sasser that has recently stepped onto the virus scene. Where firewalls really come into play is in the area of Internet or Network access.
There are two basic types of firewalls: hardware and software.
A common hardware firewall is a routers. In a small network it sits in-between your PC and modem. These firewalls feature the ability to hide your PC from others on the Internet by assigning you private IP addresses through a process called NAT (Network Address Translation) or DHCP (Dynamic Host Configuration Protocol).
I may have lost some people there who are not familiar with IP addressing. This can get confusing rather quickly. To put it simpler: a router will take the Internet address that your ISP has doled out to you and give the PCs the are connected to the router a generic private IP address (not valid for the internet). The other primary job is to close ports (these are numbers that are associated with certain jobs, for example most email clients and servers use SMTP port 25 and POP3 port#110) ports can be a vulnerability as seen in the past and a hacker can have an easy time getting into your PC with ports wide open to the world. When hackers try to scan your network for known vulnerable ports the Firewall simply drops the packets because they contain data that no PC on the network requested.
Software firewalls are a little bit different and they have good points and bad points. First let me start by saying that it is always better to have a firewall then not to. The main difference between the two styles of firewalls is that one is an external device that runs on it's own hardware. The software firewall is an application that runs on your PC. This is the one down side I believe because it's one more application running on your PC while you're trying to surf the web and can cause resource overhead and slow things down in older PCs. In concept the firewalls really are the same, except that one of the biggest differences is a software firewall doesn't have any address translation services (i.e. NAT or DCHP).
Software firewalls do have some really great features however. For instance, a software firewall is great for someone who is new to this area of PCs and wants to learn more. I say this because most of these firewalls have a reasonably easy to understand interface different from the more "Techie" looking router interfaces.
Software firewalls also have a feature for Internet access that I think is very informative, for example in most of the software firewalls I have come across when a program tries to access the internet the firewall will pop up and ask you if you want this action to be allowed every time, prompt every time, or deny Internet access to the program. Most software firewalls will also notify you when someone from outside is hitting your firewall and a lot of times you get the IP address of the party on the other end of the actions. Both of these features can be used to further protect your PC, in some cases you might even be able catch a hacker trying to get into your PC by getting their IP address and then asking there ISP what this IP address is doing pinging your IP address.
I've actually helped one of customers do this they called me up and said that there firewall kept making noises and popping up with windows saying that there was some activity on here firewall. She said that this had been going on for a couple of days. Well we opened up the interface and looked at the log describing what the activity was and from whom it originated. There were a bunch of pings hitting her firewall, but the software gave us the IP address, and from there we opened up a command line and pinged the IP address back and it came up with their ISP's domain name. She called that ISP and talked to them about this address and what has been going on. I wouldn't be surprised if he was kicked from his Internet service.

Defragmenter Program to Optimize the Placement of Files

2009-09-14T05:25:00.000-07:00

This utility program is used to re-organize the files and un-used space on the hard disk, so that operation system can access data more quickly and easily. When operating system stores data on the disk, it stores the data in the first available sector on the disk. In this case data of a file is stored on disk in a scattered form; it is referred to as “File is fragmented”. The fragmentation slows down the data accessing speed of computer. You can improve the performance of your computer by de-fragmenting your hard disk. In De-fragmentation process, the data of each file is stored in continuous sectors. There are many third party software’s available in market for this purpose but you can use windows built-in utility program called Disk Defragmenter. To start disk defragmenter utility, first make sure all running program are closed.
To run disk defragmenter utility, go to the Start button and type dfrg.msc in Run option then press ok. Now here a disk defragmenter window will appear. Select any drive and press defragmenter button. If you have a large hard disk, this process can take several hours. I recommend you doing this after one month if you want to improve the performance of your computer.

How to configure Stub area in OSPF protocol?

2009-09-03T01:49:00.000-07:00

The area feature is used in OSPF to divide a large network into small segments. Any changes in one area will not cause any problem in other areas, thus reducing routing table size and processor overhead also.
There are three main types of area:
Stub area
Totally stub area
Not-So-Stubby area (NSSA)
The main purpose of stub area is to block the flooding from AS external advertisements in OSPF and only OSPF injects a default router into a stub area. In this tip we will discuss here only about stub area and the remaining areas will be discussed in the next tips.
Follow the network topology of three different routers in given figure:

There are some common OSPF configuration and Executable commands:
In this example we will not configure router C as stub area because it is backbone router and does not participate in area 1. So we will be concerned here only with router A and router B.
OSPF configuration on Router B as stubby area
In global configuration mode
Router-B(config) # router ospf 1 (Here 1 indicates the process identification number)
Router-B(config-Router) # network 20.0.0.0 0.255.255.255 area 1 (Here 20.0.0.0 indicates the network ID and 0.225.255.255 wildcard mask with area 1)
Router-B(config-Router) # network 30.0.0.0 0.255.255.255 area 0 (Here 30.0.0.0 indicates the network ID and 0.225.255.255 wildcard mask with area 0)
Router-B(config-Router) #area 1 stub (Here 1 indicate the area ID and area 1 is designated as stubby area)
Router-B(config-Router) #exit (exit from ospf 1 on router B)
OSPF configuration on Router A as stubby area
In global configuration mode
Router-A(config) # router ospf 1 (Here 1 indicates the process identification number)
Router-A(config-Router) # network 210.100.10.0 0.0.0.255 area 1 (Here 210.100.10.0 indicates the network ID and 0.0.0.255 wildcard mask with area 1)
Router-A(config-Router) # network 20.0.0.0 0.255.255.255 area 1 (Here 20.0.0.0 indicates the network ID and 0.225.255.255 wildcard mask with area 1)
Router-A(config-Router) #area 1 stub (Here 1 indicate the area ID and area 1 is designated as stubby area)
Router-A(config-Router) #exit (exit from ospf 1 on router A)

Run vs. Save when downloading programe

2009-08-21T03:21:00.000-07:00

When you are downloading any program or file from the internet, for example any antivirus program or an email attachment from your friends. Here you will get a dialog box with three options to Run, Save or Cancel. Basically this is confirmation from a user "Do you want to run or save this file", even you can cancel it to abort the downloading.
Here if you select the Run option, only the setup file is downloaded as temp file in your computer temporary internet folder and your computer run this program setup automatically without your confirmation or virus scanning. This is unsafe for your computer if you are downloading this program from any new or unknown source.
But if you select other option Save, You can save this program on your computer in any location. Now you have the full source of program on your computer, you can scan the all program before open it.
Normally you should select the Save option, if you are downloading this program from any free software sites. You have extra security layer if you save the setup file before run it.

Router basic Troubleshooting Tips

How to set security on your Recycle Bin properties?

2009-08-19T00:03:00.000-07:00

This tip is very useful to manage the security of Recycle Bin properties because by default everyone can change the recycle bin sittings using windows default rights. If you want to restrict your users to modify these settings, simply edit the "Permissions for BitBucket" and set the read only rights for all users. Using windows registry editor you can set the Recycle Bin rights for all user.

The best technique to edit the windows registry, always backup the whole windows registry keys on backup drive before editing. Because any mistake in Registry can cause serious problem in your computer to run properly.

Follow the given steps to edit computer registry for Recycle Bin properties:

To enable this feature, you will need to be logged into your computer with administrative rights.

First click on Start button then type Regedit in Run option.

Here locate the location to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ Explorer\BitBucket

Here in left side panel, right click on "BitBucket" keys and click on Permissions option.

Now "Permissions for Bitbucket" dialog box will appear to manage the user's rights.

Here select the user name or group "Everyone" from the list under the "Group or user names" category and then allow read only permissions for selected user under the "Permissions for everyone" section.

Now click on Apply button to save these settings and again click on Ok button to finish the process.

Close the registry editor and restart your computer after any changes to go into effect.

To verify these sittings, simply right click on Recycle bin and go to "Properties" dialog box and any changes here will give you a message "You do not have permission to modify the settings for the Recycle Bin".

CONFIGURING STARTUP KEY:

2009-08-18T00:22:00.000-07:00

* Go to Start/Run and in the blank field type "syskey" press enter, or OK.

* You should see a small window titled "Securing the Windows XP Account Database". From this Window select the "Update" button to move to the next window.

* The "Startup Key" is the next window. You'll see a couple of options there, but the one we are looking for says "Startup Key on floppy disk", along with some warning about how your system is going to startup now.

* After selecting this click OK, and a pop-up will alert you that the key has been changed. Another message follows asking you to insert a disk in drive A: (Floppy drive).

* Insert the floppy, click OK, and one more window will come up telling you that the Key has been changed and you need to have this floppy disk in order to log into Windows. That's exactly what we want.

When you're all done go ahead and eject the floppy (you might want to slide the little lock up on the floppy to insure you don't format it on accident), and restart the PC. Windows will appear to come up normally, but after it loads the kernel the "Windows XP Startup Key Disk" window pops-up. Grab your Startup Key floppy put it in the floppy drive, and select OK. You'll see Windows load up and bring you to your user logon screen.

I told you this is a cool trick and really helps lock down you PC. I hope you get some use out of this, but please be careful.

Wireless Security

2009-08-17T04:34:00.000-07:00

The ability to share an Internet connection is great and the ability to do this wirelessly is even better. Wireless networks are easy to install, you don't have to run cables, and you can roam around a location within the WLAN (wireless local area network), or physical range of wireless connectivity . These features are what makes wireless networks so popular with both end users, and hackers.

The one problem with wireless networks is the vulnerability of your network. A typical hardwired network has physical security due to limited access to the actual network and one opening to the internet (Gateway) has a firewall or two in place (or it had better). This can stop most unauthorized access to your network. The difficulty in setting up wired networks has discouraged a lot of people from installing networks in the first place.

Then a long came the wireless which, as I stated earlier in the article, made the home networking game more appealing and not as intimidating. Having a wireless network means that the physical security that is inevitable in a wired network is simply not there. Anyone in the range of your wireless network can see your network, and if not secured properly, can gain access. If your wireless access point isn't the router on your network then outsiders can slip in behind your firewall. This used to happen at my college, there was an apartment complex behind a portion of the school, and the other techs would piggyback on some guy's network. He had an unsecured wireless network, no one did anything bad to him, they just used him for Internet access but he never knew.

There are some practices you can perform to insure that no one is using your connection or trying to get on your personal network. First and foremost you need to get WEP (Wired Equivalent Protection) in place, which is an encryption that stops unauthorized users from accessing your network. There are at least two encryption types in 802.11b (128bit, and 64bit) and should probably be changed every other week or so. WEP encryption used to be completely the user's responsibility, but now I'm seeing hardware out of the box with at least one encryption key configured, forcing the user to configure his PCs in order to connect.

Using WEP is essential to wireless security, but don't rely on it alone, there are other security measures you can put in place as well. With some wireless units you can set a MAC address filters, witch can really beef up your security. A MAC address is an identification number the manufacturer stamps on a network device, and is (or should be) completely unique. If this security is in place then even if someone knows the WEP Key they still cannot get into the network because your wireless access device will deny it.

There are two other things you might want to do to tighten up your network: The first thing you should do is go through and change all of the default security settings, and passwords. The reason I said this is most Routers and access points usually have a lot of these configuration fields (i.e. username and password or the SSID ) filled out with generic values for ease of setup. The bad thing about this is that people can use these settings against you to gain access into your network. Secondly, with a lot of routers your SSID is set to broadcast by default, this means that it's broadcasting your network's name to the physical reaches of your network. Not good, even if your neighbors don't have the security rights to access your network they will constantly see it every time they boot up one of their wireless PC's.

Check program before downloading

2009-08-04T09:31:00.000-07:00

Computer security can be defined as the protection of computer and its data from any loss or illegal access from other users. Normally file virus or program virus attaches itself with program files and activates when these program files are run. Infected program files are normally downloaded from Internet. When ever you are trying to download any program from the Internet, always download from trusty sites. On Internet the Software cracker or key generator sites are the main sources of computer virus.

When you are downloading any program or file from the internet, for example any antivirus program or an email attachment from your friends. You must select the Save option, if you are downloading this program from any unknown or free software sites. First scan the downloaded program before open it. You have extra security layer if you save the setup file before run it.

Different File Type from Storage point of view

2009-08-03T04:23:00.000-07:00

File organization is a technique for storing and arranging data on secondary storage devices so that it can be retrieved easily when needed. It includes the physical order and layout of records on secondary storage devices. The techniques used to write and retrieve data to and from the storage devices called it access methods.
There are main three type of files from storage point of view.

-Sequential files
-Direct or random files
-Indexed sequential file
-Sequential Files
In sequential data files, records are stored on the storage media in a sequence. No locations are specified for individual records. The records are stored in an order, one after the other. Similarly, records are also retrieved in sequential order. It means that records are accessed one after the other in the same sequence in which they are stored on the storages devices. For example, to access a particular record from a data file, all records are searched one by one until the specified record in found. Therefore, accessing records in sequential files is very slow.
-Direct or Random files
Direct files are also referred to as random files. In these files, records are not stored in a sequence. Each record is stored by specifying a particular address or location within a file. The address is calculated against the value of the key field of the record. Sometimes, the same address is calculated, which creates a problem to store record. This problem is known as synonym. Data accessing from direct files is very fast. A record is accessed directly by specifying its address.
-Indexed Sequential Files
These files can be processed sequentially as well as randomly. In these files, the location of individual record is also stored along with data of record. For this purpose, an index is created to keep the track of locations of individual records.
Index refers to the location on the storage media where record is stored. You can say that an index is just like a table that is used to find out the location of a particular record. The key fields of the records are stored separately into the index along with the address of each record. Usually, an index is created in a new file called index file. The index file is updated whenever a new record is added or an existing record is deleted. Indexed file organization is more effective and fast in accessing data from data file than sequential file organization. These files occupy more space on the storage media but accessing speed of records is same as random access files.

Scan Individual Files for Viruses

2009-08-02T10:05:00.000-07:00

We often recommend that when you download files you should scan for viruses. The same is true for attachments sent via email (although, if you have decent antivirus software this should be taken care of).
But do you need to scan your whole computer? No, you can scan just one file with most AV software (Norton, McAfee, AVG).
-Just right click the setup file and you should see "Scan with whatever AntiVirus" or just "Scan for Viruses".
-Your AV software will come up, scan the file, and let you know of any infections.
-Some newer AV also lets you scan zipped folders before unzipping.
-Knowing that it's safe, you can then proceed with installation of the program or opening the file.

Web Bugs

2009-08-01T06:40:00.000-07:00

Have you ever heard the term Web Bug? How about Web Beacon or Clear GIF? Well, don't feel left out if you haven't, it's not everyday terminology. The terms I mentioned are different names for the same thing. For the sake of remaining simple I'll stick with one name Web Bug. So what are Web Bugs and what to they do? They are small (1 by 1 pixel), usually transparent gifs hidden on websites or e-mails within other images like banner adds. Web bugs come from a different site than the one you are viewing but are most often affiliated with the site being viewed.
They are a lot like cookies in that they allow sites to recognize you and track where you've been. Web Bugs have a couple of major differences however. Web bugs share your information with any site that you may visit with the same type of web bug imbedded on it. The personal information bugs are sharing can be harmless information or very personal information, it depends on what information you have put on one of these sites. If you have given one of these sites information like your email address, then every other site you visit with the same bug will have your email address and can now send you spam. By sharing this personal information between sites these entities using bugs can get your email address and send out more spam and web bugs right to your front door. If you visit a site that recognizes you from a Web Bug then that server can not only track you but also send images and blocks of text to you. Web Bugs are also harder to detect than cookies because they are hidden, extremely small, and invisible.
These Web Bugs can also be placed in e-mails, a favorite trick of spammers is to hide a Web Bug in a random email. Opening or even previewing this e-mail can initiate the Web Bug process, which tells spammers that this is a valid e-mail address when someone views it. This validates your address, essentially making you part of their list of e-mails to spam. Most of the more recognized e-mail clients are affected by this such as Outlook Express, Gecko for Linux, Netscape, AOL, and more.
So, how do you stop or prevent these web Bugs from tracking you? As far as e-mail, make sure you don't open or even preview e-mails from unknown sources. Another thing you can do to prevent the Web bugs from biting is to block images in your e-mail all together, this will stop the GIFs from getting through your defenses. Win XP Service Pack 2 turns this setting ON by default in Outlook Express, and other e-mail clients have similar options (i.e. MSN/Hotmail and AOL).
You can also configure tougher cookie settings in your browser, but keep in mind all of these settings will affect the way you surf the web and view your e-mail. You can get advertising blocking software, but these programs have a hard time distinguishing between images that show information and images that are crawling' with Bugs. You can also go through the HTML code and look for the img tag that relates to a cookie (sounds like fun).
So are these bugs really something to get all worked up about? Well if you really don't like the thought of constantly being tracked and evaluated. If you don't like spam or pop-ups then this could be something you might want to at least regulate. You can figure out exactly what a web bug is doing by viewing the privacy policy which should be located on the website of the owner of the bug. If you don't find the privacy policy, you can always send the company e-mail and ask for what purposes do they have web bugs on their site.

Safe Online Shopping

2009-07-31T03:54:00.000-07:00

How can you tell if an online company is legit when you're thinking of buying something? Well, there are some key things to look out for:
If you get an unsolicited email about a product from a company you don't know, then DEFINITELY do your homework before you buy. Check out their reputation, or see if the same product is available from an online business you trust.
Since web addresses can change, look on the site for an address and phone number. Know where to complain or contact if you are dissatisfied or have a question. You might also want to review the Privacy Policy to make sure they won't sell your information to marketers.
Read the refund and return policy (if the website does not have one). Can the item be returned? What if it is opened? Is there a restocking fee? What about damaged merchandise.
If the site displays the BBB Online Reliability logo, click it and read the popup (hold your Ctrl key if you have a pop-up stopper) to make sure the company is currently participating.
Keep a record of your online purchase. Print out the page with the seller's name, address, and phone number. Print out the page about the item you ordered. Print any email confirmation messages you get and any follow-up messages about problems in shipping.

What kind of attachments can contain viruses

2009-07-30T04:14:00.000-07:00

Basically, anything that is executable (able to run). You're generally safe with picture files, text files, and the like. However, it still pays to scan first.
Here is a very short list of the most common to watch out for:

-exe
-zip
-scr
-vbs
-bat
-com
-pif
-asp
-doc
-xls
Those are the most common; don't misinterpret this to mean that if you get one of these files it's automatically a virus. A ".zip" file may be nothing more than a set of compressed files your friend sent you to look at. A "doc" or "xls" file may simply be an MS Office file. It's just that these type of files could also be viruses.
A couple other virus tricks you need to be aware of. First, MS Office files can contain what are called "Macro Viruses". Without getting into too much detail, these files can run a "macro" (a macro is a mini-program run from within another program) that can be as destructive as any "regular" virus. So, my advice on MS Office attachments is not to open them unless you are expecting them. If they just show up, verify with the sender first.
The other trick you need to look out for is an extra extension added to an attached file. For example, you may have something like "mypicture.jpg.vbs". In fact, if you don't have your computer set to view file extensions, it may just look like "mypicture.jpg" and omit that last "vbs" part.
This may appear to be a jpg picture file, but it's actually a Visual Basic Script file. If executed, it will happily infect your computer with a virus.
So, be careful out there.

How to Find What Virus was Removed

2009-07-29T04:48:00.000-07:00

Norton does a great job of protecting me from viruses. It will pop up and let me know that it is scanning outgoing and incoming mail. While receiving email, if the program runs across a virus it will pop up a save window letting me know where the backup file is being saved, This is usually the quarantine folder within the Norton program. With Outlook / Outlook Express simply right click the paperclip icon in the preview pane. You'll see that the attachment is called "Norton Antivirus Deleted1.txt", click the file.
A message will come up in notepad telling you the name of the infected document that was removed and what virus it contained
McAfee has very similar features: it scans my incoming and outgoing mail and it pops up to let me know when there's a threat in my email. The pop up window in McAfee also has the name of the potential virus with a link to more information concerning the virus in question.
This is nice and because you can see the threat without going though the procedure of clicking the paperclip for the name of the virus like in the before mentioned Norton antivirus. However, you can view the virus information by clicking on the paperclip like you do with Norton if you didn't catch the virus name in the initial pop up and would like view information on it.
Both McAfee and Norton have virus information sections of their website. This is a good place to take any information that you have gathered on the virus or threat, and plug it in. This can give you a really good idea about what's going on in your system and over time make you a virus expert.

Secure Website Problems

2009-07-28T08:18:00.000-07:00

You may not have the correct security settings for you to connect to secure web pages. For instance, let's say you want to get in on one of our great software specials and when you click "Checkout" you can't get to the page.
-With Internet Explorer go to Tools/Internet Options and select the "Advanced" tab. Scroll down to the bottom of the list and make sure the following are checked: Use SSL 2.0 and Use SSL 3.0
-Click the "Refresh" button (green arrows) and the page should appear.
-With Firefox you'll get a pop-up window telling you that you cannot connect because SSL is disabled.
- Go to Tools/Options, click "Advanced", and scroll to the bottom. Under "Security" check off the following: Use SSL 2.0 and Use SSL 3.0

-Click OK. Try connecting to the secure site again and it should come up.
-If you are a Netscape user you'll get a pop-up window telling you that you cannot connect because SSL is disabled.
-Go to Edit/Preferences and expand "Privacy & Security" by clicking the arrow next to it. Select "SSL" from the list. Check off the following: Use SSL 2.0 and Use SSL 3.0
-Click OK. Try connecting to the secure site again and it should come up.
-If there is still a problem, check your Firewall/Network Configuration. Make sure that the SSL port (port 443) is open. Since every setup/software is different, we can't give exact instructions. Check your manual or help file for details.
-Hopefully, though, it's just an SSL problem and you'll be on your way.

Email Security Scan

2009-07-27T04:22:00.000-07:00

The problem with all the security holes that arise from day to day is that it's hard to keep up. "Am I protected?" you wonder, "I update constantly, I scrutinize all my email messages, especially attachments, and read all of Chad's awesome security articles, but how do I know for sure?"
Well, since such a large number of security holes center around email I'm glad to announce today a service that can check your system for potential exploits. The service is a web based email scanner that you can tailor to send out over 20 different emails, each attempting to defile your system with dummy exploits. It's like hiring a security agent to go over your system and tell you what aspects of your security is in good shape, and what areas could use some improvement. When set in motion, the scanner fires off the dummy viruses and exploits to the specified email address. Don't be surprised if your virus software starts popping up with security messages, as a matter of fact, this is exactly what you want to happen; it means your system is seeing the threats coming in.
The emails themselves have message bodies describing what their particular test was for and how to make sure you're protected from this sort of attack. Some of the emails have attachments and some attempt to create text documents on your desktop, the emails tell you exactly what to do to ensure the tests ran correctly, thus providing an accurate assessment of your system's defenses.
In addition to the testing your system for security holes this is also a good way to educate yourself on some email-born security issues by getting a chance to see them in action without putting yourself in any danger.

Erase Your Hard Drive

2009-07-26T04:58:00.000-07:00

People give their old PCs away to family members, charities, and some end up at the local PC repair shop without ever being properly wiped clean. Everything stored on your PC is on the hard drive. There was a two-year experiment done by MIT graduates Ali and Eman where they collected 156 hard drives from various places (the web, ebay, PC shops, and businesses). Out of the 158 drives tested, 129 drives worked and hardly any of them were properly wiped clean. There were thousands of credit card numbers, private "adult" stuff, love letters, you name it, that was completely recoverable on these drives.
Most people believe that deleting data and then cleaning out the recycle bin does a sufficient job. This is NOT the case. When you delete something in windows, it just marks it to be overwritten. There is also a misconception that formatting a hard drive permanently erases stored data. This is also not true, a format just reconstructs the allocation table and checks the blocks on the disk. It does nothing actively to remove the data; it simply leaves it "unprotected". With both of these scenarios, if you have the right software you can recover data thought to be unrecoverable.
So, how do we erase this data on a hard drive for good? You can physically destroy the drive but that's not as easy as you think and you would be amazed at what people can recover data from. There are cases where people have drilled holes in the platters and it could still be recovered. You can take it to a PC repair store that has a Degausser that removes all the magnetism from the drive leaving it useless for good, but this can be way too expensive to justify the price for the common end user. You can write Zeros to the drive with the utilities at the hard drive manufacturer site and that will stop most people, but experienced users can still recover it.

How to solve low memory problems?

2009-07-25T01:22:00.000-07:00

Normally this warning message shows when you run many programs same time than the RAM installed on your computer is designed to support.

Tips about DSL Internet Service

2009-07-23T06:16:00.000-07:00

DSL is another digital internet connection and working with high speed than any old dial-up and cable modem. There is no need to install new dedicated cable network to run DSL because data is transmitted over already exiting copper wire. This connection is ideal for internet access. DSL provider offering traffic allowed up to 1 GB with basic 128 Kbps internet connection. But if you want to play online games, downloading audio or video files and uploading data, then the traffic allowed(1 GB) in one month from DSL provider will be the main issue for you. May be some DSL provider offering you up to 2 GB or more with the same rates. Today there are many DSL providers offering DSL connection in all cities and some rural areas. DSL provides high speed on already exiting telephone lines, and same time you can use internet and as well as your line for phone. To check the availability of DSL connection first check your telephone number at which you are want to install DSL connection. If your telephone exchange is updated by DSL provider according to need of DSL technology then you may apply for DSL internet connection. For this purpose you can visit your friends or neighbors for information to getting broadband connection. You can visit your nearest Internet service provider to check DSL availability in your area and about different DSL packages.

Back Up Your Data

2009-07-17T08:23:00.000-07:00

Just about everybody has important data on their hard drive, from digital pictures to important documents, emails, earmarked websites the list goes on and on. In my experience people are pretty lax about backing up their PCs, and I think this really is an area that deserves attention. With a good back up set you can bounce back from a fatal hard drive crash and be up and running with all the your pictures, documents, downloads, email and favorites before you know it. Having important files stored on removable media is also a good safety precaution in case you get a virus or Trojan horse.

There are a couple of different ways to back up important data, from the casual copy and paste to running complicated scheduled backups. There is no wrong way, as long you have a copy of everything you need.
You can save the data on a couple of different types of media (floppy, ZIP, CD-R/RW, DVD+R/RW, Flash memory, even dat drives) but for home use I really recommend either CDs or DVDs, floppies are just to small, Zips, although bigger than floppies are still small (100-200MB), and they're old and kind of expensive. Flash memory can store data but it's not really something you want to save data to and store away unless there is no other option. DAT tapes are more for the corporate end of things and are overkill in most homes. CDs are cheap, hold a lot of data, work on any PC and are easy to store.
If you use CD-RW, or DVD-RW you can actually save money by setting up a "round robin" with your backups. To do this, you need at lest 3-4 of the same backup set, take the oldest and erase it. Now use the blank disk for the new backup, the next time you do a backup use the oldest disk in the set and so on and so forth.
As for the methods of backing up, I find it's easiest when all my intended files and folders are organized in structured manner and not scattered all over my hard drive. This is a good way to insure that you don't forget anything important by hunting for a bunch of individual files. An easy way to stay organized is to create a descriptively labeled folder structure and try to be diligent about saving your data to it's designed folder.
Another good practice is to test your backups, don't just take the burning software's word for it. After a backup, explore the disk and randomly go through files and open them up to make sure that they're complete and not corrupt. Learn from my experience, waiting for a complete system failure is not a good time to check the validity of your backups. This is a good way to get yourself in a lot of trouble as well ?I know if didn't back up the pictures or movies of our kids I wouldn't be able to live with my self.
Once you have all your ducks in a row, it's time to back up. There are a number of ways to do this as well. The easiest is to open you burning program and select data CD and go through the folder then explorer and grab the folders you want to back up. When you select a folder you should see it in the "burn" selection window, once you done with your backup selection choose "burn".
If you have Windows XP you have the luxury of being able to open up the blank CD or DVD in Windows Explorer and copying and pasting the desired folders right onto the disk and select "Write files to CD" and Windows will do the rest for you. This is nice but not all of us have XP, and I personally still like to use my third-party software.
Most burning software has their own backup services, and there are a number of third-party back up titles out there. The nice thing about using these types of software is the options. Things like compression, backup jobs, and incremental backups. These are nice features especially when you have some backups that you want to insure are up to date. For instance, you can create a "Back up Set" which is basically a saved and named list of folders and files that you want backed up. This makes the whole process so easy?you can create a backup set and once a week or so your can run it and it will either create a new back up or save just the changes to the backup. These are two options that are usually found in backup programs. If you use "backup sets", it's important to keep the files organized, and in all the correct folders. You can also schedule Backup Jobs, which are basically backup sets that are scheduled to run at predetermined times, and intervals (i.e. once a week Friday at 6:00).

Tips about Cable Internet

2009-07-16T06:13:00.000-07:00

Normally a high speed cable Internet is better than a dial-up and some time DSL connection. A cable internet connection load web pages three times faster than a dial-up. Cable Internet's maximum speed is 2Mbps but this is not a standard , it depends upon you internet connection provider ,connection type like many option (128Kbs,256Kbs,1Mbps or more), your home distance from main router. Another main reason if you are using dedicated connection type or sharing connection type that effect speed. In dedicated connection you can use static IP address. You will probably be limited in your choice of cable Internet service by where you live, no other provider there. Some cable internet connection provider use their cable for both purpose like cable television and internet also. High speed cable Internet may have less downtime because there are no busy signals with cable Internet access, and that is why more reliable.Your choice of a cable Internet service will also depend on factors such as:what level of service you want, e.g. dedicated connection type or sharing connection type, what kind of security you need in internet connection e.g. if you are a normal user or you are running secure business like a finance company then your choice must be different to choose connection.Whether you just use the Internet for e-mail or whether use VoIP or do broadcasting/streaming audio.

Tips to use Pop up Blockers

2009-07-15T06:04:00.000-07:00

Pop-up window messages basically used for online advertising to increase the web traffic with minimum cost, but these pop-up messages can be used to damage a computer or also for hacking purpose. In routine when you are browsing the internet and suddenly a new window pop-up dialog box display with different messages for example" speed-up your internet ","free upload your files or images".

These days there are different types of cheap DSL Internet connections available in the market with different rates according the need of users, for example ADSL, R-ADSL, HDSL, SDSL, and VDSL. Monthly rates of DSL connection depends upon its speed and downloading or uploading traffic allowed. DSL providers offering traffic allowed up to 1 GB with basic 128 Kbps internet connection. But if you want to play online games, downloading audio or video files and uploading data, then the traffic allowed(1 GB) in one month from DSL provider will be the main issue for you. Visit the market for the best rate DSL, may be some DSL providers offering you up to 2 GB or more traffic allowed with the same rates. Almost all DSL providers offering per month connection with the same rate but you can minimize your DSL cost to share your connection on many computers using any Internet sharing software. Normally DSL connection is available on unlimited usage but you can also buy connection for certain amount of time or hourly packages to control the monthly spend. Finally, you can reduce your DSL cost to share the business internet connection with your home, if your business or home is located near.

Tips about Coaxial Cable

2009-07-13T06:02:00.000-07:00

Alternatives to Coaxial
Coaxial is the cable Internet standard, widely installed in business and corporation Ethernet and other types of local area network. However, other alternatives can get you online at high speeds. Twisted pair copper wire and optical fiber, better known as fiber-optic, are viable alternatives to the different coaxial cable types. However, this depends on the signal carrier technology used.
Depending on the configuration, coaxial cable may be heavier than fiber-optic cable, which is usually lightweight. However, the heavy shielding of many coaxial cables helps block signal interference from televisions and other household appliances.
Both digital fiber-optic cables and digital coaxial cable are available for use in cable Internet infrastructure, but are designed to carry different signals, optic versus electronic. It all depends on your cable Internet setup which types of digital cables you use.
-High-Band Coaxial Cables
Coaxial cable has an extremely broad bandwidth, especially digital coaxial cable, which tends to prevent loss signals. Coaxial cables have a lower attenuation and can carry hundreds of cable Internet signals. The coaxial is a relatively simple cable, yet it can carry large amounts of data. In the case of telephone and video signals, coaxial cables can handle hundreds of phone conversations and a television program taking up 3,500,000 Hz. Certainly, given this capacity, coaxial cables can handle bandwidths of 2-3 Mpbs. There is no bandwidth performance difference between the coaxial cable types.
-Coaxial Cable Safety and Maintenance
As with any wiring and infrastructure, all coaxial cable types, including digital coaxial cable, require careful handling. Although the coaxial copper shielding is strong, whether rigid or braided, it's not indestructible. Some safety and maintenance tips:
• Make sure your coaxial cables and coaxial connectors are fire resistant (FR).
• Don't buy secondhand, used or cheaply manufactured coaxial cables.
• Make sure coaxial cable shield is grounded for safety.
• If possible, house coaxial cables separately from the rest of your computer equipment and especially other cables and wires.
• Do not expose coaxial cables to water.
• Make sure the cable outlet wiring is intact.
• Keep your coaxial cables repaired with tools such as the Shake ‘n Seal Coaxial Cable Repair Kit.
-Troubleshooting Coaxial Cable Connections
Either your digital coaxial cable or your regular coaxial cable can become disconnected from the cable modem and/or the cable outlet. Check both connections if the cable Internet stops working.
If you are still getting interference from other devices in the home, replace your coaxial with the quad-shield coaxial cables. Also, interference may happen because with all coaxial cable types, the insulation degrades and the cable must be replaced. Also, the coaxial connector or splice needs to be attached to the correct copper screen to provide the return path for the cable Internet signal.
Coaxing More Speed Out of the Coax
Typically, the data transmission speed through coaxial cables is 10 Mbps. This is true for all coaxial cable types.
Can you coax more speed out of the coaxial connection, especially with digital coaxial cable? You can use a large lower-loss coaxial cable, and use the same cable throughout the signal path, to gain more bandwidth and a higher connection speed. The good news is that coaxial cables are ideal for higher bandwidths.
-Ethernet and Coaxial Cables
Thin Ethernet or 10 Base-2 is a lighter, less expensive version of 10 Base-5 or Thick Ethernet. It uses a lighter, thinner copper coaxial cable. What is the advantage of a sleeker coaxial? Besides skipping the 10 Base-5 external transceivers and simplifying the coaxial setup, thin Ethernet features well-shielded coaxial cable. The drawback is that the RG-58A/U coaxial cable used with thin Ethernet can't be interchanged with other coaxial cable types, including digital coaxial cable. Also, changing the network is difficult since the network breaks easily. Making it difficult to troubleshoot.
Despite drawbacks, thin Ethernet is a simple, inexpensive infrastructure to implement for basic cable Internet networking on a budget.
Separating Cable Signals
Your coaxial cable setup should prevent any signal interference between your television and cable modem. A coaxial cable splitter is part of your defense system. In addition to the copper shielding, signals going through your coaxial cables, including your digital coaxial cable, are separated by a cable splitter. Cable technicians will install the splitter on the side of your house and run a separate coaxial line to your cable modem. In addition, your different coaxial cable types such as triax, digital coaxial cable, twinax and biax have added reinforced casing and configurations to prevent interference with the cable Internet signal from the television signal as well as other household appliances.
-Coaxial Cable Types
Learn about coaxial cables:
Coaxial cable carries your broadband cable Internet signals. Coaxial cables are the nerves or, if you prefer, veins of your cable Internet connection. The different coaxial cable types are:
-• Rigid coaxial, with a solid copper wire sheath
-• Flexible coaxial, with a braided copper wire sheath
-• Hard line coaxial, a heavy-duty cable with rigid or semi-rigid pipe for the outside shielding
-• Triaxial cable or triax, a coaxial with a third layer of shielding, insulation and sheathing
-• Twin-axial cable or twinax, a coaxial with a balanced, twisted pair within a cylindrical shield
-• Biaxial cable or biax, a figure eight configuration of two coaxial cables
-• Digital coaxial cable, suited to any high-grade digital applications such as digital cable and digital cable Internet
Digital coaxial cable is primarily used for audio and home theater, but its powerful connectivity makes it ideal for digital cable Internet.

Wireless Hub Tips

2009-07-12T01:49:00.000-07:00

Is a Switch and Wireless Hub the Same Thing?
Yes and no. A switch can be described as a smart hub. A switch is used to connect computers and devices on a network, but is able to distinguish where to send transmissions.
Generally speaking, in a home wireless network, all you will need is a wireless hub. Larger, more complex networks, such as in offices, should consider using switches.
--------------------------------------------------------------------------------
Wireless Hub
A hub is used to connect devices on a network. A wireless hub does the same task on a wireless network. The devices can be computers, printers, etc. Typically, hubs are inexpensive and an excellent way to connect devices together on a network. If you want the easiest solution, Linksys provides wireless hubs and routers that are simple to configure and implement.
--------------------------------------------------------------------------------
Wireless Adapter
A wireless network adapter is a device that can make regular, wired devices able to communicate on a wireless network. Typical wireless adapters include wireless USB adapters and printer adapters. You can also purchase wireless adapters that allow desktops and laptops to connect to a wireless network.
Wireless adaptors can afford an office with older technology to upgrade to a wireless network thereby increasing flexibility of office design, set up and safety.
--------------------------------------------------------------------------------
Can I Share an Internet Connection With a Wireless Hub?
The short answer is no. If you have a broadband internet connection with all computers hooked up via a wireless hub, only one computer can have internet access at a time.
However, a router allows computers to share an internet connection. You can then hook up multiple computers to via a hub, but only one computer on that hub can use the internet at any given time.
--------------------------------------------------------------------------------
Wireless Adapter for Laptop
Wireless adapters are made for both PC slots and USB connectors. Both are easy to install and use if your laptop or desktop does not have a built in Wi-Fi card. Make sure to follow the specific wireless adapter instructions for configuration of the adapter.
Additionally, make sure you buy the right adaptor for your machine. Your best bet will be to bring all of the specs of your PC or laptop with you when you go to buy a Wireless adaptor. Then you are sure to get the right one - and don't be afraid to ask for help if you aren't sure what you are looking for. Better to ask then to bring the wrong thing home!
