Why
buy a
computer?
Think long
and hard as
to why you
want to buy
a computer.
Do you want
to buy a
computer to
play games,
then you
might be
better of
to buy a
game
computer
like a Sony
PlayStation?
Do you want
to buy a
computer to
go on the
Internet or
do you want
to do an
administration
of some
sort on it?
It makes a
lot of
difference
for which
purpose you
purchase a
computer as
to what
hardware
configuration
you should
look for
and the
price you
have to pay
for it.

eBay
This
document is
intended to
help make
those
choices and
hopefully
be more
prepared
when you
think about
buying a
new
computer
and get the
right
configuration
for your
needs.
If you have
children in
the age of
5 and up,
it is
almost a
must to
have a
personal
computer in
your house.
But even if
you don't,
computers
and
Internet
already
form a big
part of
today's
life and
you don't
want to be
left out of
this
progress of
new
technology
and how it
can be of
benefit to
you.
Hardware.
This
question
will be
answered in
great
detail. We
will look
at all
parts of
the
computer
and what to
look for if
you go for
those
bargains,
which might
not be
bargains at
all.
You also
want to buy
a computer
that lasts.
If you buy
a computer
that is
already
outdated,
you might
run the
risk that
you are not
able to run
the latest
software on
it. A
computer is
as fast as
it slowest
components.
This means
that you
can have a
fast
computer,
but if a
component
like a hard
disk slows
down the
computer,
you might
have just
wasted lots
of money on
a high
speed CPU
that will
never be
fully
utilized.
That's why
this
document
also talks
about some
technical
specifications
that might
be
important
when
selecting
the right
machine for
you.
Additional
features.
We will
also talk
about
additional
hardware,
like
printers,
scanners,
digital
cameras,
modems and
networks.
The right
additions
might get
more use
out of your
computer
for only a
little bit
of extra
money.
Software.
We will
also take
some time
to look at
some
software
features
and what's
best to buy
when you
are just
starting
out.
Where to
put the
computer.
The best
spot to
install
your
computer is
the living
room. This
way, if you
have
children,
you have
control
over what
they do on
the
computer.
Also a
computer is
an
instrument
to make
life
easier. A
computer
can be used
to play
with but it
can also
help do
your home
work, help
you find
information,
and become
more
creative.
Problems
and
Support.
The time
that you
would
probably
find that
there was
anything
wrong with
a computer
from a
hardware
point of
view is in
the first
month that
you operate
your
computer.
If your
machine is
running
okay for a
couple of
months, it
will
probably be
okay for
ever
(figuratively
speaking).
You can buy
a computer
from a
company
like Dell,
Compaq or
Gateway and
get
technical
support
with it. I
have only
had good
experience
with
Gateway's
technical
support
service as
long as you
keep buying
everything
from them
(both
hardware
and
software).
As soon as
you buy
something
through
another
source,
they will
not support
it and tell
you to
contact
that
manufacturer.
Computer
options,
hardware.
CPU
The CPU
(Central
Processing
Unit) or
Chip is the
heart of
the
computer.
There are
many
different
types of
CPU's and
with
different
types of
speeds and
this
already
determines
how fast
the
computer
will be and
what the
capabilities
of your
machine
will
have.
Older
computers
might still
have 486
CPU's but
all new
computer
have a so
called
Pentium
chip. These
Pentium
CPU's come
in
different
brand names
and
different
types and
speeds. You
have Intel
Pentium II,
Pentium
III,
Celeron,
and AMD
Athlon and
Duron CPUs.
The speed
can vary
from 300 up
to 1200 MHz
(1.2
GHz).
What does
this all
mean and
what is
right for
you? You
should
compare
this with
buying a
car. If you
do not need
the speed,
why would
you buy a
Porsche?
And if you
can do with
a Ford why
buy a Rolls
Royce? The
most
expensive
CPU's are
the Intel
Pentium III
and Athlon
processors.
The more
the
megahertz
the more
expensive
they
become. For
just normal
use
(writing
letters,
playing
basic
games,
desktop
publishing)
a 500-600
MHz CPU is
very fast.
But if you
can afford
the money,
you might
be better
off buying
something a
little
faster, so
that future
software
that needs
more brain
power can
still run
on your
computer.
We
recommend
that you
buy a
Celeron,
Pentium
III,
Athlon, or
Duron based
computer in
the 600 -
1000 MHz
range.
If you
intend to
use only
the basics
of the
computer,
like typing
letters,
going on
the
Internet
and doing
some basic
desktop
publishing,
other types
of
computers
can be
purchased
as low as
$400 (new)
or $150
(used)
excluding
monitors.
You might
also want
to look
into the
newly
emerging
Internet
appliances
or Web
TVs.
Recommended
CPU:
Celeron or
Duron bsaed
computer
fror the
more cost
conscious,
Pentium III
or AMD
Athlon for
the power
user.
Current
desktop
systems are
no slower
than 550
MHz. For
more
information
on
selecting a
CPU,.
Memory.
Buying
system
memory
(RAM) for
the
computer is
important
for the
overall
performance
of the
computer.
Programs
are loaded
from the
hard disk
and stored
into the
computer's
memory upon
usage.
Whenever a
program is
stopped,
the program
is stored
from memory
back to the
hard disk
again.
Not enough
system
memory will
result in a
state
called
swapping.
This means
that the
hard disk
will be
used as
additional
memory, but
since a
hard disk
uses
mechanical
parts, the
overall
performance
of the
computer
will
degrade.
It is also
important
to have
memory that
has the
same speed
as the rest
of your
components
(like CPU).
Memory
comes in
many
different
forms; EDO,
SDRAM, DDR,
and Rambus
DRAM.
Again, the
faster the
memory, the
higher the
price.
If you have
a 486
computer,
EDO memory
is fast
enough, but
a Pentium
III 450 MHz
needs the
special PC
100 memory
to keep up
with the
CPU, or
else the
performance
will
degrade.
More memory
makes your
computer
faster too.
To go from
64 MB to
128 MB will
cost you
about $ 60
and will
increase
the
performance
of your
machine if
you intend
to have
high
usage.
Recommended
Memory.
64MB-128MB
for all new
computers.
Hard
disk.
With the
hard disk,
both speed
and size
matters. In
terms of
the brand,
I would
personally
stick with
the leading
brand names
like IBM,
Seagate,
Western
Digital,
Maxtor.
With hard
disks there
are
basically
three
different
types,
EIDE, SCSI
interface,
or
firewire.
For SCSI
and
firewire
drives, you
need a
separate
interface
card and
the hard
drives
themselves
are more
expensive,
but faster
then EIDE
drives.
Within EIDE
you have
three
different
types,
regular
EIDE, Ultra
DMA and
Ultra ATA.
The
difference
is that
Ultra DMA
and ATA
have higher
speed in
terms of
accessing
and data
transfer
since the
hard disk
runs faster
(DMA 5400
RPM, ATA
7200 RPM)
and because
of a
special
interface
the data
transfer
rate is
higher (66
MB/sec, or
100
MB/sec).
The access
to data on
the disk
(seek time)
is very
important
for the
overall
performance
of the
computer.
Data
transfer
rate is
important
if you are
using big
files like
big
databases
or video
files. Hard
drives are
relatively
cheap, for
instance
the
difference
between a
10 GB and a
20 GB drive
is only
$70.
Recommended
hard disk:
10-30 GB
Ultra DMA
7-9 ms seek
time, 512 K
Cache, 7500
RPM.
Video
Card.
Video cards
are the
interface
between the
CPU and the
monitor.
The latest
technology
has
delivered
very fast
video
cards. They
are the so
called AGP
or
Accelerated
Graphics
Port video
cards. The
data
transfer
rate
between the
CPU and the
Video card
has been
improved
since the
motherboard
now comes
with a
special
dedicated
slot (AGP)
for the
video card
that runs
faster than
the PCI
bus. Most
video cards
also have
their own
video
memory
installed
on the
card, which
increases
memory
performance.
There are a
lot of
different
brands and
types of
video
cards. You
have to
compare
your own
intended
use of the
computer
with the
capabilities
of the
video
cards. If
you plan to
do video
editing or
computer
aided
design or
3D games,
you need
different
kinds of
video
cards,
depending
on what you
want to do
most. Good
brands for
Video are
ATI,
Diamond
Multimedia,
Creative,
and
Voodoo.
Recommended
Video Card:
2X-4X AGP,
16-64 MB
RAM, 3-D
card with a
good brand
name.
Sound card
and
speakers.
It does
matter a
lot in
terms of
quality of
sound,
which sound
card is
installed
in the
computer.
One thing
is that it
has to be
compatible.
Lots of
games come
equipped
for most
common
sound
cards, but
if the
system has
an strange
sound card,
at least
make sure
that it is
Adlib
compatible.
A sound
card and
its quality
really
becomes
important
when you
want to
work with
sound, e.g.
connect a
midi
keyboard or
record
sound
through
your
soundcard
onto the
computer.
There are
many brands
of
soundcards
and the
quality of
the
soundcard
is mostly
reflected
in number
of bits; 16
bit, 32
bit, 64 bit
or 128 bit
sound
cards. The
soundcard
that I have
personally
had the
best
results
with are
the ones
manufactured
by
SoundBlaster.
Speakers
are
personal. I
advise
someone to
go to a
Best Buy or
CompUSA and
listen to
different
computer
speakers. I
personally
like the
Cambridge
SoundWorks
with
subwoofer,
good
quality
sound for
reasonable
price.
Recommended
sound
cards:
Diamond MX
300, 400,
600 and the
family of
SoundBlaster
Live
cards.
CD-ROM.
CD-ROM
drives come
in three
different
basic
forms, the
standard
CD-ROM, the
DVD ROM and
the
ReWritable
CD-ROM.
The
standard
CD-ROM is
read only
and can
read
standard
Music
CD-ROM's,
data
CD-ROM's up
to 700 MB
of data and
are in
various
speeds.
32X, 48X,
72X
etc.
DVD-ROM, is
a different
kind of
CD-ROM that
can read
the same
kind of
CD's as a
standard
CD-ROM, and
on top of
that it can
read
DVD-ROMs.
One single
DVD-ROM can
store up to
6.4 GB of
software
which is 8
times the
size of a
conventional
CD-ROM.
DVD-ROM
also gives
you the
possibility
to view
Digital
movies on
your
desktop,
although
you also
require a
so-called
MPEG
decoder
card. This
sometimes
comes as
part of the
DVD set but
most of the
time needs
to be
purchased
separately.
A CD
ReWritable
gives you
the
possibility
to record
your own
CD's, both
data and/or
Music up to
800 MB of
data or 80
minutes of
music. The
speed of
writing a
CD is from
to 2x to
12x. At 2x
speed it
takes 1
hour to
record 800
MB of data,
at 12X it
takes less
than 5
minutes.
CD-recorders
can be
purchased
for as low
as 90
dollars and
blank CD's
are
approximately
1 dollar
each. A
great way
to make
backups,
copy
software
and create
your own
music
CD's
Recommended
as optional
equipment:
1 DVD-ROM
10X (if you
want to
watch
movies) and
1
CD-ReWritable
8X/32X or
faster (for
backup or
recording
music).
Modem.
Modems are
used to
either
connect to
the
Internet
through a
phone line
or send or
receive fax
documents
through a
phone line.
Most
computers
come with a
modem. Most
modems are
56K V.90
modems
which
indicates
the speed
of the
modem. 56K
is the
maximum
speed you
can achieve
with a
so-called
dail-up
modem. To
get more
speed for
Internet
usage, you
will have
to go to
ISDN or
Cable modem
connections.
Top brand
modems are
3Com, Zoom,
or U.S.
Robotics.
Modems can
be
sensitive
to current
fluctuations
and need to
be
protected.
This can be
done by a
surge
protector
that
protects
both power
and
telephone
outlets.
Recommended
modem: good
brand 56K
V.90
Monitor.
Buying a
monitor for
your
computer is
almost a
separate
study.
Monitors
can vary in
price
between 130
to 1500
dollars.
Important
factors in
the price
determination
are the
monitor
size and
viewable
image,
maximum
resolution
and refresh
rate and
the dot
pitch. With
Windows 98,
a second
monitor can
be attached
when a
second
Video card
is
installed
creating a
two-monitor
size
desktop.
The monitor
size (for
example 19
inch) means
that the
viewable
size
(measured
diagonally)
is about 18
inches. The
smaller the
dot pitch,
the greater
the
resolution,
e.g. an
0.25 mm
pitch is
sharper
then a 0.28
mm pitch.
Everything
over 0.28
mm is not
considered
super VGA.
Another
important
factor is
the refresh
rate. This
is the rate
in which
the image
is built up
on the
monitor. A
higher
number
(85Hz)
gives a
steadier
image then
a lower
number
(60Hz).
Recommended
Monitor: 19
Inch (18
inch
viewable),
76 Hz
refresh
rate, 0.26
mm pitch or
less.
Keyboard
&
Mouse.
The
keyboard
and mouse
are very
personal.
Some people
love the
ergonomic
keyboards
and some
keyboards
have a
different
click then
others. Go
and feel
which
keyboard
and mouse
are best
for you.
You can
also buy a
cordless
mouse and
keyboard,
which work
on
infrared.
Again, a
very
personal
choice.
Recommended
Keyboards:
Microsoft,
Logitech,
or
IBM.
Additional
Features.
Printer.
You have
two types
of
printers,
laser or
inkjet.
Laser
printers
are more
precise
then inkjet
printers
and print a
lot faster
then inkjet
printers.
The down
side is
that they
are black
and white
only.
(Color
laser
printers
are still
very
expensive).
Color
inkjet
printers
give you
more
flexibility
in terms of
your
printing
work since
you can add
color to
your end
result. My
personal
recommendation
is to buy a
HP color
inkjet
printer.
They give
the best
results in
terms of
quality,
durability
and least
use of ink
cartridges.
Buy a HP
color
inkjet with
photo
printing
technology.
Recommendation:
HP Inkjet.
Epson and
Lexmark
printers
are also
good.
Scanner.
With a
flatbed
scanner,
you can
scan color
photo's and
black and
white text.
Printed
text can
potentially
be
converted
to
documents
without
having to
reenter the
text and
color
images can
be used to
add to
documents,
send over
the
Internet,
etc. You
can buy a
scanner for
- 40
dollars.
Important
is the
resolution
of the
scanner and
the ease of
use of the
software
that comes
with it. I
have had
good luck
with the
Microtek
scanners.
Scanners
can be
connected
via the
printer
port or via
the
so-called
USB
(Universal
Serial
Bus). If a
USB is
present on
the
computers
motherboard,
it is
recommended
to use this
over
reusing the
printer
port.
However, we
do not
recommend
you add a
USB port to
an old
computer
just to run
a
scanner.
Recommendation.
HP or
Microtek.
Network.
If you have
more then
one
computer
(or desktop
and laptop)
you can
install a
network.
This
connects
multiple
computers
together.
You can
share
printers
and
hard-disks
/ CD-ROMs
through the
network and
play
certain
games
through the
network. A
network is
not
expensive
and windows
95/98/2000
has
standard
network
software
built-in.
You can
install a
complete
network
between two
computer
for less
then 100
dollars.
Digital
Camera.
Most of the
good
quality
Digital
cameras are
still
pretty
expensive.
You are
probably
better off
buying a
good
flatbed
scanner.
Don't
expect the
quality of
a digital
camera in
combination
with a
color
inkjet to
give you
the same
result as a
developed
picture,
but they
are getting
closer and
closer.
Still it
avoids the
inconvenience
of having
to use
special
software
and cables
to download
pictures to
your
computer.
<I have
had great
luck with
my Olympus
D-450 Zoom
. I used it
to take the
pictures in
our Adding
a Second
Hard Drive
article.
With a
digital
camera, you
definitely
get what
you pay
for. I
would
recommend
that you
get at the
very least
a 2X
optical
zoom camera
with a
resolution
of no less
than
1280x960.
The optical
zoom is
important
to bring
objects
closer to
your
camera. The
resolution
is
important
for keeping
the pixel
size small
in your
printed
pictures. -
Ed>
Game
controller.
To be able
to play
games, you
can either
use your
keyboard as
a control
device or
connect a
game
controller
to your PC.
Game
controllers
come in
many
different
varieties
and vary
enormously
in price.
Purchase a
game
controller
that is
compatible
with most
games and
that is
easy to
use.
Software.
Operating
system.
For a
single
processor
system the
choice is
pretty
simple.
Windows 98
Second
edition or
Windows
Millennium
Edition.
They are
better then
windows 95
and if you
are
thinking
about
multiple
screen
support,
you can
only do
this with
Windows 98
or higher.
If you have
windows
3.1, even
on
diskette,
you can buy
the upgrade
rather then
the full
version.
Windows Me
has the
added
feature of
system file
deletion
protection,
enhanced
networking,
and system
restore
protection.
During the
install,
Windows 98
and Me will
ask for
verification
of
purchased
Microsoft
products,
simply
insert the
windows 3.1
diskette
and the
install
will
continue.
The upgrade
version has
all the
features of
the full
version.
If you want
to use two
CPUs on one
motherboard,
then Linux,
Windows
2000, or
Windows NT
is a must.
Also, if
you have an
older
computer,
Windows 95
is usually
a better
choice than
Windows 98
or
Me.
Office
tool.
There are
various
office
tools like
Lotus
Office
Suite (with
Ami-pro and
Lotus 123),
Corel
Office
(with Word
Perfect and
Quattro
Pro) and
Microsoft
Office 2000
(with Word
and Excel).
The most
compatible
and most
used in the
business is
Microsoft
Office.
Anti-virus.
A good anti
virus
program is
a must
these days.
Buy one
that also
protects
email and
downloads
from the
Internet if
you are
going
online. The
advantage
of McAfee
over Norton
is that
McAfee does
not charge
for virus
information
files
updates,
Norton
does. You
do need to
download
the latest
anti-virus
information
at least
once a
month.
You can
download a
free
version of
Aladdin's
eSafe virus
protection/Internet
firewall
software
at
www.esafe.com
. This is a
great
all-around
virus
protection,
email
monitor,
child
protection,
drive
restorer
program. I
have been
using it
for a
couple of
months and
it seems to
be as good
as any
virus
protection/Internet
security
program out
there. You
can even
update it
for
free.
Another
choice, if
you already
have a
virus
checker, is
the free
Zone Alarm
personal
firewall
from Zone
Labs. This
program is
used with
your virus
checker to
prevent
online
attacks.
Zone Alarm
can be
downloaded
free
at
www.zonelabs.com
.
Desktop
Publishing.
There are
various
desktop
publishers,
Adobe
Pagemaker ,
Microsoft
Publisher
2000 and
QuarkXPress
($770 ).
Unless you
are a
professional
Desktop
publisher,
I think
Microsoft
Publisher
is good
enough.
Possibilities
to make
flyers,
brochures,
booklets,
newspapers
and small
magazines.
Photo
editing.
Again lots
of
different
choices
with
different
options.
Aldus photo
styler,
Adobe
Photoshop
LE ($95 ),
Microsoft
Photodraw
2, Paint
Shop
Pro.
Recommendation:
Adobe
Photoshop
LE or Paint

6.
Printshop /
Creativity.
These
programs
allow you
to make
greeting
cards,
banners,
labels,
crafts and
come with
lots of
clipart
(color
drawings
and
