How Fast, How Big: Everything Computer Buyers Need to Know
By PETER H. LEWIS
A fter nearly a quarter-century of intense research by many of the
greatest technical and marketing minds on the planet, personal
computers still force the average consumer to decipher an
eyeball-glazing catalog of technical mumbo-jumbo like this, from a
recent newspaper advertisement: "ATX w/300 Watt PS, 48x CD Rom, 9.1
GIG LVD U2W 2MB Buffer, 128MB PC100 ECC RAM, Intel PIII 500 w/Fan,
8 MEG ATI Xpert 98 AGP, 3Com 905TX 10/100 NIC. . . . "
No wonder the Apple iMac has been such a popular computer. Until
recently, the most daunting task for iMac buyers has been choosing
a color: Blueberry? Grape? Tangerine?
Some day, probably early in the next millennium, most computers
will be as easy to buy as the iMac. The recent emergence of
so-called information appliances, Web pads, smart phones and
new-generation PC's is encouraging.
There will always be people whose socks roll up and down in
excitement when they see a list of technical specifications for a
new PC, just as there are those who care passionately about the
cubic inches, cylinders and horsepower of an automobile engine, or
the combined slugging percentage and on-base average for baseball
players. For many people, especially professionals, the megahertz
and megabytes are worthy of intense scrutiny.
For the rest of us the goal is merely to get the best deal on a
personal computer that will meet our computing and communications
needs, and budget, for a few years before it becomes obsolete. To
make that choice easier, I offer a guide to buying a personal
computer.
Keep in mind that almost any personal computer sold now has more
than enough power to handle tasks like word processing, e-mail,
keeping a calendar, managing a contact file, balancing the
finances, playing games, running educational software and so on.

Compaq Presario 5900Z-700 - For the inveterate gamer, this Compaq
computer, with a 700-megahertz Athlon processor, includes 128
megabytes of RAM, a high-speed 27-gigabyte hard disk, a 10X DVD drive,
a 4X CD-RW (rewritable) drive, 32 MB of graphics memory on a Creative
3-D Blaster TNT-2 Ultra graphics card, a 19-inch monitor, a Klipsch
Promedia THX surround-sound speaker system and a D.S.L. modem. All for
$2,912 on Compaq's Web site.

But the real value of a PC is not as a calculating engine but as a
communications device. Sending and receiving e-mail has become the
most commonly cited task for personal computers, followed closely
by doing research on the Internet. An Internet connection harnesses
the resources of millions of computers worldwide and transforms an
ordinary desktop PC into the most powerful and versatile knowledge
machine available to the average person.
Increasingly, even traditional disc-based computer applications
like educational software and games are being enhanced by online
links to the Internet.
So no matter what computer you choose, get a modem. To oversimplify
it, a modem is the telephone that a computer uses to call the
Internet over regular phone lines. Specifically, get a 56K modem,
often called a V.90 modem.
Better still, for those who plan to spend a lot of time online and
who have access to a high-speed cable or digital subscriber line
(D.S.L.) Internet service, get an Ethernet card. Cable and D.S.L.
are the two leading options for connecting to the Internet at
speeds many times faster than a 56K modem. Such services require
something known as a Network Interface Card, or N.I.C. An Ethernet
card fits the bill. Macintoshes come with Ethernet cards.
BRAND NAME The differences in actual components used by the major
manufacturers are minimal. Any decent byte mechanic can screw
together off-the-shelf components to make a PC that works just as
well as one assembled by a multinational corporation. The real
issue is how well the PC maker deals with you before, during and
after the sale. Experienced PC users who need no hand-holding can
find good deals from clone shops. For beginners, I recommend
staying with one of the big companies, even if it costs a bit more.

Apple iMacDV - DV or not DV? That is the question when trying to
choose among the three new models of iMacs from Apple. You could go
for the $1,299 iMac DV (digital video) in one of five colors or, if
your budget permits, the stylish gray iMac DV Special Edition at
$1,499. The slot-loading DVD drive lets iMac DV owners use CD-ROM
discs, play CD audio discs and even watch DVD movies.

In the most recent PC Magazine survey of service, reliability and
support, only I.B.M., Dell and a smaller vendor, Quantex, earned
Readers Choice "A" ratings for desktop computers. I.B.M. and Sony
topped the list for notebook computers.
WINDOWS VERSUS MACINTOSH The choice between these operating
systems is almost religious in nature.
Mac users are in the minority but believe that they are a click
closer to heaven.
Windows could be described as a digital code version of a
Hieronymous Bosch painting, but it has a monopoly on PC sales, or
so the judge says. Both systems are more complicated and unstable
than they ought to be. Once you get online, it matters less and
less.
And now for the more specific stuff.
MICROPROCESSOR There are no practical, functional differences
between the market-leading Intel and Advanced Micro Devices chips,
or the less common Cyrix chip, for that matter.
Intel makes two flavors, the basic Celeron, which is a good value
for home PC's, and the advanced Pentium III, which is favored for
games, multimedia and more demanding professional applications.
The Advanced Micro Athlon chip is an impressive performer and
represents the most serious challenge to Intel's hegemony. Do not
buy anything slower than 350 megahertz unless you plan to replace
the PC soon. Do not buy anything faster than 600 MHz unless you are
spending someone else's money or are seriously into video and
playing games.

A PC's real value is as a communications device.

MEMORY RAM, or random access memory, is system memory. When people
ask how much memory your computer has, RAM is what they usually
want to know. Typically measured in megabytes, RAM is like your own
memory: It works great when you are awake (the power is on), but
evaporates when you go to sleep (the computer is shut down). More
RAM is better, because it means the processor does not have to run
to the filing cabinets so often, which slows things down. So if you
can afford it, pile it on. If the budget is tight, it is better to
upgrade the RAM and downgrade the processor. Do not buy less than
64 megabytes of RAM. Get 96MB if you can, or 128MB if you have used
the word "multimedia" in a sentence more than once this week.
Another important kind of memory is called Level 2 (L2) cache,
which mainlines data to the processor at high speed and improves
system performance. The important thing is that there be an L2
cache. The amount, usually measured in kilobytes (for example,
512KB), falls under the more-is-better rule, but any is better than
none.

DELL DIMENSION XPS T500 - For the budget-conscious, this $1,339 system
includes a 500-MHz Pentium III processor, 64 MB of RAM with 512
kilobytes of Level 2 cache, a 6.4 GB hard drive, 16 MB of video memory
on a Voodoo 3 graphics card, a 48X CD- ROM, a 17-inch monitor, Harman
Kardon speakers, a 56K modem, a floppy drive and a year of Net access
_ backed by Dell's reputation for reliability.
_________________________________________________________________
Video or graphics memory is another type. Make sure your system has
at least 4MB of this kind, or, if games and multimedia are
important, 8MB. Some larger monitors need more than basic video
memory.
STORAGE If you are like me, it is imperative to write things down
lest they be forgotten. That is where storage comes in.
Most personal computers come with a hard disk drive, whose capacity
these days is typically measured in gigabytes (GB). Do not get less
than 6 GB.
If you plan to save a lot of digital photographs or MP3 music
files, or are a compulsive pack rat, go for 10 GB or more.
Almost all computers today come with a CD-ROM drive. Some PC makers
tout their CD-ROM speed, like 40X or 48X, but in general anything
over about 20X is superfluous.
If you can afford it, consider replacing the CD-ROM drive with a
DVD drive. It does everything a CD-ROM drive does, including
playing CD audio discs, but it also transforms the PC into a DVD
movie player.
Hard disks fail, although not as often as they used to. Inevitably,
they fail when you forget to make a backup of your data files.
Backing up your files is the computer equivalent of brushing and
flossing your teeth, only more important.
Floppy disks are fine for backing up a handful of important files,
but now that hard disks are measured in gigabytes, it would take a
bushel of 1.44MB floppies, and hours of time, to make a dent in
one's backup duties.
Instead, get a Zip drive, which stores 100 MB on a relatively
cheap, removable disk. Zip drives get the job done. For more fun,
however, get a CD-RW recordable drive. But I'm running out of
space, so that will be discussed in a future column.
MONITOR The new standard is 17 inches. Once you have opened a
bunch of World Wide Web pages, you will understand why anything
smaller is a pain.
If desk space is tight, or if budgets are loose, consider a new
flat-panel monitors. A 15-inch flat panel offers the same screen
size as a 17-inch conventional monitor.
PORTS The computing world is shifting to Universal Serial Bus
(U.S.B.) as a common standard for connecting printers, scanners and
other peripheral devices.
The U.S.B. connections are faster and easier than the older serial
and parallel ports. But then remember to buy U.S.B. peripherals.
