Picture yourself using your new computer. You might think you
know nothing about computers, but you'll be surprised by your preconceived
ideas and preferences. Is your ideal system a desktop or a laptop?
Are there are a variety of peripherals such as printers and scanners
and external speakers connected all over? How large (or small!) is
the monitor?
Why do you need a computer? The first and probably most
important thing to do is have a clear idea of your purpose for buying
a computer. For example, do you want it for simple word processing
or do you need it for a broad range of tasks like spreadsheets,
access to the Internet and multimedia applications? This will help
you determine what software and hardware you need for your computer.
Background reading: If you don't know much about computers,
do some background reading so that you have an understanding of
the basic components and how they work. Scan the computer sections
of newspapers, PC magazines, check with user groups, library and
Internet resources.
Shopping checklist: Things to keep in mind
- Ask family and friends about computer systems and suppliers
that worked for them.
- Be careful not to compare computers based on price only. A computer
with a 6GB hard drive is always going to be cheaper than one with
a 16GB hard drive.
- Compare the specifications of equipment you're after and whether
it will operate the software you need or is compatible with other
equipment you are currently using.
- Check out the cost of consumables for the equipment being offered.
The low cost printer may have a high cost to replace the toner
cartridge.
Speed: Decide the performance level you need from your computer.
This depends on what you plan to use it for. Computer games, multimedia
and desktop publishing software require a faster computer whereas
simple word processing software can run satisfactorily on a less
powerful computer.
The performance level your computer is capable of is determined
by a combination of variables: the Central Processing Unit (CPU);
the Motherboard; the amount of Level 2 cache (high speed memory)
installed; the memory installed; and the internal hard drive. Beware
of 'overclocking'. This is the practice of adjusting the processor
to run at a speed faster than its original specification.
Memory: Make sure your computer comes with enough Random
Access Memory (RAM) to efficiently operate your software. RAM is
measured in Megabytes (MB).
Storage capacity: Make sure the hard disk has sufficient
storage capacity to store your information and programs. Storage
is measured in Megabytes (MB) or Gigabytes (GB).
Ability to upgrade: You may want to consider buying a computer,
which is upgradeable. This means that you will be able to replace
existing components with up to date and faster components at some
stage in the future. You need to be aware, however, that the ability
to upgrade your computer may cost you more and that in some instances
buying a new computer can be cheaper than upgrading your old one.
Pre-installed software: Sometimes the software you purchase
is preinstalled. If this is the case you should always make sure
that you are also given the original media (e.g. diskettes or CD
Rom).
Pirated software: Make sure the software supplied is not
a pirated copy. Pirated software doesn't generally come with disks,
instruction books (if they do they are usually just photocopies),
and a license to use the software or help from the manufacturer
if you have problems. If you erase the software and you don't have
the diskettes, you won't have any way of restoring it.
Shareware: Many of the software 'bundles' on the market
come with shareware. Shareware is software that is offered to users
on a trial basis. This software is provided on the condition that
if you use it on a regular basis you will send a payment to the
authors. Manuals for shareware may come on a CD or floppy, but more
often than not, as a downloadable file from the Internet.
Anti-Virus Software: Viruses are hidden instructions, which
can move through networks and operating systems and become embedded
in programs. They can destroy data or display messages. It's a good
idea to purchase anti-virus software. This is particularly important
if you plan to use Shareware and the Internet, as your chances of
picking up viruses are greatly increased.
When purchasing anti-virus software you should also make arrangements
to be kept up to date on the availability of new anti-virus software.
Availability: Make sure the goods are in stock, If not,
get the retailer to give you a firm date when the stock will be
available. You may wish to make the purchase of your computer subject
to the computer being available by a certain date.
Taking delivery: Before taking delivery of your computer
it's a good idea to open the boxes and make sure that all the components
are actually there. Some consumers ask the store to have their computer
set up and working properly before agreeing to accept the goods
or making their final payment.
