When
I buy a computer what do all
those hardware numbers mean?
Well most of the terms here are in the first question about
computer terms, but to be specific:
1) The speed of
the CPU is measured in Hertz. The older systems were going in
the 200 -> 800 Khz, and we thought that was wondrous.
Today's systems, and I need to say when I am saying this: June 2004 are
now in the next level of GHz and over the 3 mark. In today's
market I would say the average computer in WalMart is about a 2.8+ GHz
computer. You don't need to get too caught up in this speed
value as other "bottlenecks" in your system, or internet
connection, will most probably negate the need for more speed in
processing. If you are not going to be doing video
editing of your home movies, state-of-the-art video games or running
big-time photo editors (e.g. PhotoShop 5) then a computer above 1 GHz
should be fine for you. Understand, that in this fluid industry
this may change in a couple months, so if you want to be safe, then
move the 1 to 2 Ghz.
2) The amount of MEMORY
in
your system is in MB's.
However some new systems are now in the next level also and provide a GB of memory or more. If as state above
you are not a "hard-core" user, then 512 MB's should be fine for you (If
you run out of "hard" memory you can configure
your system to use excess disk space as "memory", called the "Page File").
3) Hard DISK SPACE is also
in MB's and GB's.
Disks today come in much larger storage capacities and read/write
speeds. As the above, a basic system only needs about a 20
GB hard disk. If you are of the type that does not
houseclean your system then go for the 60+ GB disk.
4) Your MODEM if you are
going dialup will probably be a 56K (baud rate)
V90 model. However, you should understand that dialup baud
rates are actually based upon the capacity of your local phone
companies phone lines and the noise there on. If your ISP
provides 56K V90 support you will most likely never see that occur as
the phone lines generally cannot support that.
5) The rest is optional and
the list is long:
floppy
drives, CD
drives,
CD/DVD drives, video
cards, color video monitor, sound
cards, intranet cards,
wireless
cards, external memory,
zip drives, etc. These are too many and too
complicated to discuss here.
Quickie Nomenclature Table
MHz, GHz = CPU speed
MB, GB = Memory size and Hard Disk size
Kb(ps) = baud rate of Modems
Mbps = speed of your Network card
What should you pay for a standard
level PC? Did I say that!?! That requires
another widely variable answer. Depending of course what's in the
machine, maker of PC, where you buy it and when you buy it. I
will list a machine that would be considered low-end generic, yet
should be
able to handle most common computing applications of today. I'm
not going
to get into which maker of PC's is better than the other -- ask around
for that answer. Also, remember, what you are going to
use the machine for is very relavant to what size machine you need,
i.e. someone who is only going to surf the internet and do email needs
a much smaller/powerful machine than someone who plans on doing video
editting or wants to play the latest video games.
This is a bench mark only, i.e. this is only a estimate and the cost
should decrease with time, so you will need to interpolate from this
date: June 1, 2004
Cost: $500
