How do
I decide what type of PC to buy?
When buying a computer it
depends on what you wish to use it for. This will affect the price you
would expect to pay. Start by listing main the tasks
you will want to do on your computer. Is playing the latest 3D action
games a priority, or do you only want to type letters and keep your
accounts? Your priorities could make a big difference to the type of
computer and extra peripherals (printer, scanner, speakers, etc) that
you need to buy. As well as your "essential" list, it is
also a good idea to make a secondary "possible" list of
non-essential - but desirable - computer activities.
When you have
make a list of what you want to do with your new pc, you will be
in a better position to decide what hardware and software you will
need for the job. This will also need to be balanced against your
available budget. To get the best possible deal, it helps to learn
about some of the technicalities yourself rather than to rely solely
upon a computer salesman's recommendations.
Processor
The Central Processing Unit (CPU) is
the "brains" of your computer and controls the speed at
which it processes information. In terms of computing power, it is the
most important element of a computer system. Processing speed is
measured in megahertz (MHz) and the higher the number, the faster the
PC. There are various types of processor on the market. The two main
competitors are Intel and AMD.

Pentium 3 - Intel's
Pentium 3 is currently the most popular processor. It is a
good general "workhorse", comes at a reasonable
price and has a long lifespan.

Pentium 4 - Intel's
Pentium 4 is designed for high performance computing,
including video and audio streaming, digital image processing
and games. If you only need to run standard office programmes,
Pentium 4 is overkill.

Celeron - Based on the
Pentium 3, the Celeron is built for the low-end sector of the
market. It is relatively cheap and suitable for surfing the
Internet and using basic programs like word processors and
spreadsheets.
|
| • |
Athlon - AMD's Athlon
range is equivalent to the Pentium 3. The Athlon XP processor
now competes with Intel's Pentium 4.

Duron - At the lower
end of the home and small business markets, AMD's Duron is
equivalent to Intel's Celeron processor.

Hard Drive
Your hard drive is where your PC stores your work, files and programs.
Hard drive space is now measured in Gigabytes (GB). When considering a
hard drive size, bigger is definitely better. 80GB is a bare minimum;
100GB or greater is preferable if you intend to edit graphics or
video, or plan to install a lot of games.
Memory
The memory (RAM or Random Access
Memory) is where your computer stores the information it's currently
working on. The more memory in your computer, the faster it will run.
RAM is measured in megabytes (MB). Software today requires a lot of
memory, and a reasonable starting spec is 512MB. However, if you are
using graphics-intensive programs, you should consider doubling this
to 1 GB. High-end systems currently run with 2 GB (gigabytes, or 2,000
MB) of RAM.
