First thing you should know is, all of them will get you online or network your computers together. The difference lies in speed, connection quality and more important today, security.

802.11a offers one of the fastest wireless home networking speeds because it runs on a much higher frequency that few other home electronics like phones and microwaves can interfere with. It can also accommodate more computers connected simultaneously – which is why more businesses use it since it’s unlikely a typical wireless home networking setup requires so many connections. So this sounds like the perfect solution right?

Yes and no. The high frequency apparently is its worst feature as well. Many experts will tell you higher frequencies are easily absorbed and result in shorter ranges. It also means it’s less able to overcome obstructions like walls.

That’s not all. 802.11a and 802.11b are two separate frequencies so if you have a notebook computer capable of connecting to only 802.11a networks, it won’t work in a 802.11b setup and vice versa. But, this is probably one of your least worries because many wireless connectivity hardware today are capable of connecting to either one.

802.11b uses a lower frequency. So that expands the connection range but that also means it shares the airspace with other electronics and will likely experience much more interference. On top of that, experts advise that 802.11b networks are weaker when it comes to encryption and security. Also, as you expand your range, you’re also more prone to people trying to crack into your network from further away and more concealed places. That’s certainly an interesting point.

Finally, but definitely not lastly (there are many more 802.11 variations than presented here), is 802.11g. This is somewhat of a hybrid of the two earlier standards. First it uses the same frequency as 802.11b so, you get the benefit of a wider range. Secondly it’s capable of much faster speeds like 802.11a. The third plus is it’s also compatible with 802.11b networks. So you don’t have to get new hardware to make connections with an older network or newer network (depending what you have currently). And, since it’s a newer standard, encryption is also better, and that means you can better secure your home network.

However, 802.11g wireless home networking hardware still costs more to set up than 802.11a but considering the many plusses it has going for it, this is at time of writing the best choice for your wireless home networking setup. Besides, there are plenty specials going on, prices are coming down rather rapidly for both routers and network cards.

Every person who uses a personal computer will eventually face the challenge of data recovery. Computer hardware and software can be temperamental from time to time. Hard drives and other mechanical components of personal computers and servers do not last forever, and when they fail recovering your data can be difficult, time consuming and costly.

If you are working diligently away on a document or spreadsheet in Microsoft Office and the power goes out, you may still be able to recover the documents you were working on when the lights come back on. This type of data recovery is relatively easy and straightforward. Software manufacturers recognize that power outages are inevitable and unpredictable and most office applications incorporate what is known as autosave features. At set intervals, the documents you have open are saved to a cached file. They remain in that cached state and should be accessible once your power is restored. Simply opening Microsoft Word or Excel will usually bring these documents back. For instance, when you open Word after a power failure or a software error, you will be presented with a document followed by the word recovered in parentheses. This is the document you were working on at the most recent autosave point. You may still lose a couple minutes worth of work this way, but it sure beats having to go back and retype the entire document.

If the recovered document does not appear automatically, search your hard drive for files ending with tmp. Look for one created close to the time of the power failure or software error and open it. This is most likely the document you had open at the time. If this method of data recovery does not work, you may need to follow the steps listed below.

Of course not all data recovery is so easy and so straightforward. If you delete a file accidentally, it is a simple matter to recover it from the recycle bin. Once you empty the recycle bin, however, things become more difficult. The deleted file still resides on your computer somewhere, but the pointer that tells the program where to find the file is now gone. There are various software tools available that promise to help recover deleted files, and they all have their strengths and weaknesses. Some of the major players are Norton, McAfee and Computer Associates. There are a great many smaller vendors as well.

Even if all these products fail to recover your data, you may not be completely out of luck. Data recovery services specialize in recovering data from failed and corrupt hard drives. These data recovery services have tools and equipment not available to the general public.

Government and law enforcement forensic teams will often make use of these advanced data recovery techniques to investigate cases of computer crime. Businesses also will turn to a professional data recovery service to recover mission critical data from damaged hard drives.

It is important to choose a reputable firm any time you need to have data recovery services performed. The firm you choose should be able to provide references from previous clients. You should make sure to follow up with the references they provide.

The cost for the data recovery service will vary according to the type of equipment and the difficulty of the job. You should get several estimates to make sure you are paying a fair price for the service you receive.

The first symptom that shows us your PC has got some problem is an error message. For example you get a pop-up box on your screen, a Window message, asking you to send an error report and says the application will be subsequently closed. Error messages just tell you that something is wrong so that you can then work at getting to the cause of the problem. When you get an error message try to analyze the situation in respect to what you were doing when you received it. Write down the error code. At times error messages can be very bewildering. For example: you want to open some file but it’s saying some other application is using that specific file. If you do get error messages like this then it is time to question some of your recent activities such as:

* Did you install any software or hardware recently?

* Did you install anything from the Internet?

If you have installed some software and after this your PC has become unstable, by using System Restore you can remove any system changes that were made after the last time your PC was working properly. It automatically creates restore points (or system checkpoints) when you make a change to the system. If your PC has become unstable after you made some changes, open system restore, choose a restore point, and return your computer to its previous stable state. To use the System Restore utility:

1. Click Start

2. Point your cursor to Programs.

3. Point to Accessories

4. Point to System Tools

5. Click System Restore and follow the instruction on the wizard.

If the error messages or the recent history of your PC doesn’t provide much information to you, you have to explore your PC in some of the following ways:

1. Scan you system for viruses, Trojan horses, spywares or other malwares.

2. Use a Process Explorer (freeware program) tool. Windows Task Manager shows which processes and files are currently being used and how much memory they are using, but some process names aren’t clear. Process Explorer not only gives all this information to you but also tells you which application started a process and which resources that particular application is currently using. It also has a potent search capability that quickly shows which processes have particular handles opened or DLLs loaded so that you can close any unwanted application. Process Explorer works on Windows 9x/Me, Windows NT 4.0, Windows 2000, Windows XP, Server 2003, and 64-bit versions of Windows for x64 processors.

3. Go through the error log file created by Dr Watson. Dr. Watson is a program that is used to help detect, debug, and log errors that are encountered while Windows or Windows programs are running. It automatically creates a text file when an error is detected. When running Windows 2000 the error is logged under the file “drwtsn32.log” or “user.dmp”, and when running Microsoft Windows 95, 98 or ME the file is logged with a .WLG file extension and stored under the \Windows\Drwatson or \Documents and Settings\All Users\Documents\DrWatson folder.

4. If you are having a networking-related problem you can use a Network Diagnostics system utility tool. You can run various tests using this so that it can collect different types of information. It scans your system to see whether you have network connectivity, and whether or not your network-related programs and services are running.

By going through these basic procedures hopefully you will find out what’s troubling your PC, and once that is known you can commence treatment.

Firstly, an organisation needs to clearly define its requirements – how many people would use the network, how many would use it locally (within the office) and how many might require remote access (from a different location), how many computers and other devices (servers, printers, scanners) would be connected to the network, what are the needs of the various departments and who would be in charge of running/managing the network. It also helps if one can anticipate the direction the company would take in the near future so potential growth can be factored in during computer network installation.

The technology issues should also be ironed out in advance – hardware, software, servers, switches, back-up devices, cables and network operating systems. Make sure you have the required licenses to run the software on all your machines before installing a computer network. Alongside computer network installation should proceed the building of a dedicated technical support staff, either within your own organisation or outside consultants. Delegate responsibility clearly for network management. Before installing the network, you also need to choose the security mechanism to protect corporate data and keep viruses at bay.

The transition to a new or upgraded computer network can bring some teething problems. To minimise chances of confusion, the company might need to train its staff to make them familiar with the new system. Careful planning will to a large extent prevent crises like system downtime and network crashes.

If you are planning to install a computer network or upgrade and existing one, contact Viper System at sales@vipersystems.co.uk for help.

First remember to check for the most obvious

signs of trouble,such as loose connections at

the rear of the computer for external modems.

Internal modems may have their retaining screw

at the expansion slot loose or missing.Phone

line connections may simply be inserted in the

wrong connector.

Nearly all internal modems are inserted into

the PCI or Peripheral Component Interconnect

slot in the system unit.

NO POWER AT THE MODEM

For Internal Modems,first try inserting the modem

in a different PCI Slot.Re boot the computer and

click on Start,Control Panel,and click the Phone

And Modems icon.

Then click on modems,properties,and look for

the statement “This Device Is Working Properly”.

You can click on Diagnostics and run a test to

see if the modem has power as well.

External modems can be checked for power by

inspecting the adapter plug to see if it is plugged

in completely.Look to see if any indicator lights

are flashing.

Be sure the surge protector or wall outlet is

providing power by plugging in a lamp or a

radio.If the radio works,the culprit may be

the adapter or the external modem itself.

If you purchased the modem in your town,you

may have the chance to return it to the store and

ask the technician to test it with a known good

power adapter.You can been replace either

the adapter or modem.

MODEM DISCONNECTS OFTEN

If your modem,whether internal or external,is

working but disconnects from the Internet very

often,without warning,check to be sure your

call waiting option is not enabled.

Another culprit that cause this headache is

line noise.This noise and interference can

be caused by such things as loose wiring.

Poor waterproofing,old wiring,worn phone

jacks are other causes of line noise. Make

sure no other equipment is using the same

line that your modem is on.

Be sure other devices as your fax machine,

answering machines or even security alarms

are not sharing the same line as your modem.

Other PCI devices may be causing conflicts

with your modem.Clicking the Control Panel

,and clicking the modem icon will show the

message “This Device Has A Problem” or

somthing similar if there is a conflict.

Windows will offer ways to resolve the conflict.

Take the time to carefully follow instructions

to correct any conflicts that may be present.

MODEM IS PRESENT BUT WILL NOT WORK

The external and internal modem must have

device drivers installed before they will work.

Bad or incorrect drivers can cause the modem

to disconnect as well as not work at all.

If you noticed that the device driver was either

missing or corrupt in the modem icon,follow

the instructions to update the device driver.

If some cases,you may have to completely

remove the old modem from thw Windows

Device Manager.

Once it has been removed from Windows,

reboot the computer and Windows will detect

the modem and automatically re-install the

the device driver.

If your modem came with an installation cdrom

or diskette,use the software on the disk rather

than the one in Windows.

Once you are up and running,the first thing you

should do is to visit the modem’s support web

site and search for any software patches or

updated drivers to download.

COMMON BROADBAND PROBLEMS

The most common high speed internet problems

whether its dsl or cable connections are not being

able to log on and poor signal.

If the Cable modem often reboots,you should check

to see if your signal indicator is strong.If the signal

seems good,electronic signal from mobile phones

and other devices nearby may be interfering with the

signal.

Other causes may be the main wiring to the modem

may be faulty.The vacuum cleaner or the power tools

your son is using in the garage may be causing the

problem as well.And we cannot omit the idea that the

cable or dsl modem themselves may be faulty.

While you’re learning about your computer,understand

the modem at every level and do so now while it is still

in good operating order.Print or write down modem

and all troubleshooting tips.

Put these troubleshooting tips in a binder or at least in

a safe place so you can refer to them should your PC

fail to boot.Knowing about your computer takes time

and effect but you be glad you took the time should

Imagine that you have been working on a file for the entire day and there was a power surge that caused your computer to ‘black out’. It would have been a frustrating experience for us as we had put in a lot of time and effort into it. I am sure that many of us would have experienced data loss in some form or another and have learnt to be wiser to backup our data to avoid any form of data loss.

Have you ever thought of a worst case scenario where a fire broke up and destroy your computer or where your laptop got stolen? Should that happen, the first thing that comes into your mind is the thousands of dollars that you spend on your computer or laptop and you would feel very upset about it. However, when you thought for a second moment, you started to realize that what is really valuable are the amount of data that you have built up over the years in it. Though hardware can always be replaced, even at no cost to you if you have insurance, but lost data is gone forever.

Lost data such as the thousands of mp3 and movies that you have downloaded from the Internet, thousands of digital photographs that are impossible to replace are lost in an instant. This form of data loss hits home especially hard when the laptop holds the lifeblood to your business. Imagine all your business contacts documents and contracts that you have painfully built up over the years would be vanished just like that. Your business would be wipe out overnight.

Do not wait for the worst to happen before you start to consider about data backup.

How do we keep Internet communication simple? Let’s start by taking a look at the different methods used to communicate on the web. It is important to understand the nuances and benefits of the different forms.

Email

This is the most popular communication method. Users typically use desktop software to receive, read and respond to messages. Some users use web-based mail and manage messages in a web browser like Internet Explorer. The downfall to email communication is that anyone can send email messages to anyone else if they have (or guess) the correct email address. This system’s Achilles heel is its simplicity and universal popularity.

Email accounts are often burdened by spam or unsolicited email. Despite software developers having created complex spam filters and legislators having introduced new anti-spam legislation, the problem persists and spam continues to burden email as a messaging medium.

Email Clients - http://www.messaging-software.net/e-mail-client-software.htm

Spam Software - http://www.email-software.org/spam-filter-software.htm

Instant Messaging

Instant messaging allows users to “chat” in real time. Users can send text messages to anyone online and receive instant replies if the user is also online. The “instant” fad gave way to parental fears as children made “friends” online. With no way to confirm if “friends” are who they represent themselves to be, and multiple security holes, instant messaging has taken a back seat in internet communication.

Instant Messaging - http://www.instant-messaging-software.com

Blogs

Online journals and daily diaries have taken hold. Some blogs are interactive, allowing users to respond and comment on posts. Locating topic-specific blogs that provide relevant and interesting content on a daily basis can be a challenge. The nature of a blog is to contain fresh public content. As our lives become more complicated blogs are often abandoned, as they require constant updating.

Blog Connections - http://www.blog-connection.com

RSS

RSS is the latest messaging medium and shows genuine promise as a means to communicate. RSS files are produced as XML files and are designed to provide content summaries of news or information. The biggest benefit to RSS is that it does not have the spam issues inherent to email; users opt-in to the RSS feeds that interest them.

RSS Specifications - http://www.rss-specifications.com

Forums / Newsgroups

A forum is an online discussion group. Forums can be newsgroups, or they can be web-based discussion groups. Forums have proven themselves as valuable business resources - often creating communities of customers helping customers. Without moderation and oversight they can potentially create an unfriendly environment.

Message Board Software - http://www.messaging-software.net/message-board-software.htm

Listservs

Liststervs are mailing list programs for communicating with other people who have subscribed to the same list. Using e-mail, you can participate in listservs pertaining to your topics of interest. When you submit a message to the server, your message is relayed to all on the listserv. You receive messages from other participants via e-mail.

Yahoo Groups - http://www.yahoogroups.com

What’s Next?

Internet communication is intrinsically tied to the hardware options available. Wireless technology has accelerated the development of messaging software, opening the market to a dizzying array of devices for web access. Where we were once tied to a keyboard and mouse, we will soon be navigating the web with our voices from a moving automobile, or browsing via screens in our eyewear, with tiny cameras reading our eye movements to move the cursor and make selections. Our interactive conversations will include more and more participants at once. Evaluating the many options and choosing what works best for you is the first step to effectively communicating on the web.

The purpose of most of these devices are to control how the network passes around information. This information is sent in the form of “packets”. I will refer to the term packet several times in this article. It simply means the data that the network is transporting. I will now explain the purpose of the major components of a home network.

What is a Hub

A hub is a device that has several Ethernet ports on the back of the device. One of these ports will likely be labeled “Uplink”. This port allows you to connect multiple hubs together, if you run out of ports on your hub. If you do not have an uplink port on your hub, the hub can not be easily extended if you run out of ports.

A hub is a device that attaches multiple computers on an Ethernet network. If you have a number different computers that you want to connect together, you could connect each to the hub. Any packet that is sent out by any computer on the network will immediately be transmitted to the other computers. Each computer will determine if the packet was really intended for it, and filter out packets that were intended for other computers.

You really should not use a hub in a modern home network. You should always use a switch in place of a hub. Switches will be discussed in the next section.

What is a Switch

A switch is a device that has several Ethernet ports on the back of the device. One of these ports will likely be labeled “Uplink”. This port allows you to connect multiple switches together, if you run out of ports on your switch. If you do not have an uplink port on your switch, the switch can not be easily extended if you run out of ports.

A switch serves the same function as a hub. It allows you to connect multiple computers together, so that they can exchange packets. However, a switch is much more efficient than a hub. A switch will only send Ethernet packets to the computer that the packet was intended for. Because of this you should always use a switch in place of a hub.

What is a Router

A router is a device that has several Ethernet ports on the back of the device. One of the connectors will be labeled WAN. You should connect the WAN port to the Ethernet connection on a broadband source, such as a cable or DSL modem. The other ports on the router can be connected other computers or switches/hubs that will share the WAN connection.

Routers allow you to share your broadband connection with multiple computers in your house. Rather than connecting your computer directly into your cable or DSL modem you connect the router to the cable or DSL modem. Now any computer that you connect to the router will have access to the Internet.

If you run out of ports on your router you can always connect an additional switch to the router. To connect a switch to a router simply connect the switch’s “uplink” port to one of the routers Ethernet ports. Of course, don’t connect to the router’s WAN port. The WAN port should only be connected to something such as a cable or DSL router.

Some routers come with additional features installed. Most routers also include a firewall. Firewalls are discussed in the next section. Some routers will also include a wireless access point (WAP). The WAP allows you to use wireless devices, such as wireless laptops, with the Internet.

What is a Firewall

A firewall controls traffic flow between your network and the Internet. A firewall can be either hardware or software. Windows XP SP2 or higher includes a software firewall. A hardware firewall is included with most routers.

A firewall is a very good idea. It can protect you from inbound virus attempts. By inbound virus attempt I mean other computers that will connect to your computer and attempt to infect your computer. You do not want to run a computer directly connected to the Internet, without a firewall. There are just too many other computers out there that can connect and infect you without you even noticing.

What is a Network Attached Storage (NAS)

A network attached storage device is s device that allows a hard drive to be shared across the network. This hard drive is NOT attached to any of your computers. It is simply made available by the NAS. This can be a convent way to add a hard drive that can be accessed by several computers on your network. The other common way to add a network hard drive is to simply share a folder on one of your computers. However, with the NAS, you do not need to keep one of your computers on at all times.

There are two types of NAS commonly available. The first type comes with a build in hard drive. The second accepts a USB or Firewire external hard drive. The advantage to using a USB or Firewire hard drive is that you can upgrade the hard drive if it ever were to become too small.

What is a Print Server

Just like you can buy a device to allow you to share a hard drive, you can do the same with a printer. A print server connects directly to your printer. Your printer is then shared to all of your computers on the network. This is convent because you do not need to leave the printer hooked to a computer, which must be turned on to print.

Conclusions

As you can see there are many different components. Perhaps the final component that I have yet to mention is the cable. These components are connected together with CAT5 Ethernet cable.

You are now ready to pick out the components for your home network!

Generally there might not be any reason to worry about all these files in your computer, but what if you sell your computer and all that information is left for someone else to see. Maybe friends and relatives visit and use your computer and you dont want everyone to know what files you are running on your computer. Then you are going to want to know how to delete these files.

Even if you are not worried about privacy on your computer, you may be surprised to realize how much hard drive space all this information takes up. If you are running out of drive space, you may want to delete these files.

How can I delete these files?

For Internet Explorer 5 and above, you can follow these directions to clear out temporary files and delete cookies.

1) Open Internet Explorer and click on Tools

2) Click on Internet Options

3) On the General Tab, in the middle of the screen, click on Delete Files

4) You may also want to check the box “Delete all offline content”

5) Click on OK and wait for the hourglass icon to stop after it deletes the temporary internet files

6) You can now click on Delete Cookies and click OK to delete cookies that websites have placed on your hard drive.

To clear the Internet History in IE:

1) Open Internet Explorer and click on Tools

2) Click on Internet Options

3) On the General Tab, in the middle of the screen,click on Clear History

4) Click OK

To clean up other temporary files on your computer in Windows 98 or higher:

1) Click Start, Programs (or All Programs), Accessories, System Tools, Disk Cleanup

2) Choose the correct drive usually C:\

3) Check the boxes in the list and delete the files

This deleting method is only good if you want to free space, because normal file deletion only removes a file’s directory entry, and leaves the data contained in the file on your hard drive, which can be easily recovered by any average computer user using a undelete utility. If you delete cookies or if you delete history using conventional methods anyone can recover them! Even after a hard drive format, files can be recovered using expensive hardware and software which use forensic latency track analysis algorithms.

There are several good utilities such as http://www.amicutilities.com/privacy-guard/

Computer memory is simply a storage area for the program code and the data that program uses. Computer programs use RAM to write and retrieve information, allowing for fast data retrieval and manipulation.

How Much RAM is Enough?

Simply stated, the answer is, as much as possible. Keep in mind, though, once you’ve reached a certain upper limit, which is determined by the computer program(s) used, investment in more memory will see a diminished return.

Adding more memory is one of the best ways to maximize computer performance. If you compare 2 identical computer systems, the one with the most memory will over-all be the faster. More RAM allows the computer to place more program instructions into memory, relying less on the slower hard drive.

Think of 512 Megabytes (MB) as the base standard for a modern computer. With that you can multi-task (run several applications concurrently). For instance, you can check email and download MP3s, without noticeable sluggishness.

Some applications, however, are more memory-hungry than others. Graphics programs, for example, are notoriously greedy. Memory needs are further exagerated by the operating system used. Microsoft Windows is far more demanding than, say, Linux. Currently, most PCs use Windows, though.

Should you notice your computer slowing down, consider adding more memory. Before committing to that option, however, try de-fragmenting your hard drive with a utility (program) designed for that sole purpose. A fragmented hard drive is a common cause of stalled computer performance.

Types of RAM

Right now DDR SDRAM is the most popular memory module. DDR stands for Double Data Rate, which means that the memory can be accessed twice per clock-cycle. SDRAM, the acronym for Synchronous Data Random Access Memory, has been the standard for memory modules for nearly a decade.

To add memory to your computer, you must install modules with the correct contact layout. Before purchasing new memory, you must know which type your motherboard will accept. The most common form factors are 168 pin, 184 pin and 200 pin.

You’ll also need to know whether there are slots available on your motherboard. If all the slots are already in use, you’ll have to replace 1 or all of the current modules with higher capacity ones. If there is at least 1 free slot, you can simply buy a new memory module and insert it in the empty slot.

A word of caution: whereas some motherboards can accept either SDRAM or DDR SDRAM, the 2 types cannot be mixed. You must decide on 1 or the other. Check the motherboard manual first to determine which kind of memory your computer requires.

And finally, when you are ready to install your brand new memory module, make sure of 2 things: the power is off (for your safety) and you are electrically grounded (for your computer’s safety).
