Confused about DSL? So was I at one time! However, it is no big deal to get an understanding about what it is, how it works and how it compares to your other choices for getting high speed internet access.

Faster and faster dialup telephone modems were all the rage, until DSL and cable modems came about. We can laughingly look back at those old slow modems and the tell tale dialing sounds that you could hear as they attempted to log on.

You may also wonder why DSL needs a telephone connection. Simply put, the telephone company has special equipment in place to handle DSL traffic. Even though it operates on your existing telephone line, it does not interfere with your regular telephone service. You will never know that DSL is operating in the background.

Once you upgrade, you will wonder why you ever bothered with the slow way. You will equate it to walking backwards.

You will need a relatively newer computer to be able to use DSL. Do not worry though; the requirements are not that high. However, if you have a really old machine you will need to get a better one. You will not be sorry you did.

The minimum requirements are a Windows 98 operating system, a 233 MHz machine, a CD drive, 64-128 MB memory and either a USB or 10Base-T Ethernet port. There is no need to worry if you do not understand any of that. You can always use your existing computer connection to have your computer checked for compatibility.

Just follow the link at http://paradisewireless.com/dsl.htm and you’ll easily find the systems requirements area where they will check the computer to be sure it is compatible. You do not have to sign up or download anything either. Merely click the link and they’ll do the rest. If everything is OK you’ll get a message that says “Congratulations, your computer meets the minimum system requirements necessary to run DSL”.

Besides a decent computer, you will also need to somewhat near the DSL office. It is even possible that your neighbor can get DSL while you cannot. You can also do a preliminary check online to see if you should be able to get service.

There are some other factors that may limit your ability to get DSL in your present location. Basically, it might work and it might not. But, as your telephone provider upgrades it may be possible in the future.

Getting high speed internet access with a cable modem is usually less finicky than DSL. However, cable access usually comes at a higher price.

To install DSL on your computer is not hard. If you sign up for it online, you will get an installation kit in the mail. Give your self at least an hour for the process. Open the box, unpack the modem and look at the install directions. Follow the directions in the order given and you should have no trouble.

If your installation does not work, call the support line. If they cannot assist you in getting it to work, just send it all back. Be patient and do not let anything or anyone intimidate you.

If DSL works for your situation, then you will be very satisfied. A fast internet connection is something that you can only fully appreciate once you have experienced it. You will never want to go back to dialup.

We live in an age of technology and as such we are always looking for ways to make life easier or ways to make things look better. In the home or office (or even the home office) making things look better involves getting rid of clutter. This is where the wireless desktop comes into play. No wires means less clutter and because when using Bluetooth wireless devices line of sight is not needed, you can use your desk space to its optimum with no worries.

There is more to the wireless desktop than you might think as well. You will all be aware that you can get a wireless keyboard and mouse. But wireless technology and Bluetooth in particular stretches much further than that. Your mobile phone if a recent one will probably have Bluetooth technology built into it. This means that you can easily connect it to your PC. Companies such as Logitech offer software that really gets your mobile phone and your PC working together. Synchronization is just one aspect of this, but how about being able to type an SMS text message on your keyboard and send it without having to touch your phone. This is all possible with the power of Bluetooth. Communication with your mobile phone is not the only method of contact with Bluetooth. You can also get Bluetooth headsets that work with Microsoft Messenger so you can add an easy chat functionality to your desktop. As new products come on the market Bluetooth becomes more and more popular. Peripheral devices such as Printers and Scanners can now be found.

The Wireless Keyboard and Mouse

This is the first device that you will probably buy for your wireless desktop. This is the basic starting point and probably the most effective. The keyboard and mouse wires cannot be hidden away from sight as they have to be straight in front of you. plus limiting the mouse wire can mean limiting the mouse movement as well. So A wireless keyboard and mouse will give you a better looking desktop as well as freedom to move your keyboard where you want it. You can have it on your lap or anywhere else in range. Having a wireless mouse will also help in gaming. Most wireless mice are just as responsive as corded ones and your wire wont snag at that vital moment when online gaming.

Wireless Printers

While printers are not being produced as wireless as yet. The idea is very much being worked on. Currently what you can by for your USB connected printers is a two small connecters that plug into your printer and USB port which connect together like a wireless network. Its almost a wireless USB connection if you like. I doubt that is how it will be described though. The advantages of the wireless printer as well as the lack of wires behind your PC is the range can be increased as well as you being able to place your printer in a place where a USB cable would be unsuitable to travel. A second advantage would be that connecting your printer to a wireless network for sharing will be much easier.

Wireless Networking

I think the biggest advantage of wireless technology has to be Wireless Networking. While Bluetooth technology is does not have the range in which to be affective at networking computers together. RF technology is still used however and is very easy to setup. For a simple network (peer to peer) on two computers all you need is two wireless networking cards setup to the same channel. More complex networks can also be setup using a server and workstations. Anything you can do with a wired network you can do with wireless technology.

While we keep saying that the main advantage of wireless technology is that you don’t have wires lying around everywhere, this is more true than ever when we are talking about wireless networking. When your computers are likely to be located in different room, the last thing you want is for wires to be laid around your home or office being an eyesore. Plus should you wish to move your computer at anytime, you don’t have to re-route the wires connecting your network together.
Security on Wireless networks is set by adding a name for your network which all computers on that network must be assigned to connect to, plus then you can add a password to keep unwanted intruders out from your files. Software firewalls are also recommended on wireless connections (as well as wired) just for added security against unwanted virus’ or Adware/Spyware.

Wireless Headphones / Microphone

Wireless headphones are readily available from many manufacturers. These are really one of the most practical uses of wireless technology behind the networking. Wireless headphones allow you to freely listen to your music, game or whatever noise your PC is making anywhere in your room without the restriction of wires. Even if your wires are long enough they will still be a little dangerous stretched across the room. And we all know you like to dance around your room listening to your favourite tracks. A set of wireless headphones could save you a few quid on broken items that your headphone wires have snagged on and brought crashing down to the floor .

Wireless Speakers

Wireless speakers are poking out of the woodwork and those of you that have a 5.1 or above sound system will just how many wires are involved in that setup. Not only do you have connection to the computer but each speaker is connected to the sub / power box and and you also have the volume control to deal with. At time of writing this the US seem to have a decent supply of wireless speakers where as only a few can be found in the UK. I am very sure that wireless speakers will become a lot more popular in the UK over the next couple of months. Wireless speakers will remove loads of wires from the back of your computer. Using a 5.1 wireless system will allow you to place your speakers in the perfect position without any restrictions or ugly wires running along your walls or floor.

The motherboard is the heart of any computer. It is that big flat board inside the computer that everything is connected to. It performs the role directing information and connecting components. A motherboard is often overlooked when choosing components. This is a scary thought as the motherboard determines system performance as much as every other component.

Choosing the right motherboard does not have to be a problem, even though there is a lot to consider. We will start off with the larger parts and move onto the things that are less essential.

Firstly is the socket type. The socket is where the processor (CPU) connects to the motherboard. There is no compatiblility between sockets, so it has to be the right one. The socket connection needs to match the connection of the processor you have or the one you intend to buy for the computer.
Most older Intel Pentium 4s utilize socket 478. Newer ones use socket 775. AMD chips utilised socket A for a long time, but now the AMD Athlon 64 series and Semprons use socket 939. Just check with someone as to what yours or your intended one will have.

Your choice of chip will have a lot to do with your needs, but choosing one with an up to date socket type will ensure slightly longer motherboard life as you can upgrade the chip for a while.

DDR is the RAM of choice for most systems, but some newer systems, which includes all Pentiums with socket 775 use DDR2. These two kinds are not interchangable and have a different number of pins. Both DDR and DDR2 come in different speed ratings measured in MHz. DDR has a usual 400MHz denoted as DDR400 or PC3200, while DDR2 can go a little higher and comes in slightly faster speeds. Just make it match what the board needs.

A motherboard must be chosen carefully, to both match all the other components and fit in the case you choose. A little bit of research before you buy will save a lot of hassle later on.

Picking the parts for your computer is one of the most important things in building a computer, because you cant assemble a computer without the parts! Picking parts for computers has become much easier than before, because things have been standardized, however, you need to make sure everything will fit. The first thing to think about when choosing the components for your computer is what you are going to be using it for. If you are creating a computer for just checking your eMail and using word, you are going to need much diffrent parts than a computer that you are going to be using for gaming.

CPU
The first thing you should pick out about your computer is what CPU you are going to use, because it determines what motherboard you are going to get, which determines what other components you get. There are two main CPU manufactruers, Intel and AMD. Both have their Pros and Cons, but they are pretty similar. I would suggest using AMD, because they give you a little more bang for the buck.

Here is a brief overview of the diffrent Intel and AMD CPUs:
Budget: AMD: Sempron
Intel: Celeron D

Midrange: AMD: Athlon 64
Intel: Pentium 4

High End: AMD: Athlon64 X2
Intel: Pentium D

If you are spending below $500, I would suggest a budget proccesor, Between $500 and $1000, midrange and $1000 and above I would suggest a high end proccessor.

Motherboard
Choosing the right motherboard is vital to building your computer. First, make sure you find a motherboard that has the right socket type for your CPU. Then, check the diffrent features of the motherboards you are looking at. If you arent going to buy a video or sound card, make sure your motherboard has onboard video and/or sound. Other things to check for on your motherboard are the hard drive interface, graphics card interface, expansion slots, the memory size and speed. Also, check for the chipset. There are too many to talk about, but generally Intel and nVidia chipsets are better than the other ones. Now that you picked out your motherboard, you know what to look for in your other components.

RAM
Getting the right speed and amount of RAM is vital to the speed and stability of your system. If you are running XP, you will probably need at least 256 or 512Mb of RAM. If you are going to be doing anything memory intensive, gaming, rendering or just want a faster computer, you should get 1Gb. Make sure your motherboard has enough DIMMs and the right type of DIMMs for your RAM. Also, be sure to check the speed and CAS Latency.

Hard Drive
Now its time to pick your hard drive. There are few variables in picking a hard drive. The first, and most important is size, 120Gb is usually enough for most people unless, you are going to be storing alot of pictures and video. Also, make sure you get an HD with the right interace that fits your motherboard. Almost all motherboards have IDE, but some have SATA (Serial ATA) Which is a much faster hard drive interface and uses a thinner cable which helps with airflow in your case. There is even SATAII now, which is twice as fast. Also look at speed, almost all desktop HDs are 7200RPM and Cache, most are 8Mb, dont buy a HD below those standards. If you want to spend some money, you can get 2 HDs and run them in RAID which increases performance.

Video Cards
If you are going to be doing any gaming, be sure to buy a video card, if youre not, onboard video is fine. The first thing to check for is the interface, most are AGP or PCI-E. I personally like nVidia cards better. If you are going to be doing graphic intensive games, I would suggest at least a 6600. If you have alot to spend, go with a 7800.

Optical/Floppy drives
Another thing you are going to is a CD drive, most are IDE. Get a DVD Burner if you are going to use it. Also, you should get a floppy drive, they are only $10ish and you might need it to install drivers when building your computer.

Case and Power Supply
Make sure you have a sufficient power supply!! If you have a high end computer, you should get a 450W PSU. Otherwise, 350W should be fine for most people. Most cases are ATX, but make sure it is the same type as your motherboard (ATX, MicroATX, BTX, etc…).

Be sure to make sure all your components are compatible!
