The microprocessor, or as most techs call it, the central processing unit (CPU), is

the thing that enables a computer to compute. Everything else on the computer

can be considered part of the CPU’s life-support system. So what does the CPU

do? If you believe the hyperbole of popular culture, the CPU is some sort of ma

chine brain that’s always on the verge of declaring “I think, therefore I am” and

trying to take over the world. Don’t let them kid you—computers don’t think!

What the CPU does, and does amazingly well, is add numbers. The CPU is really

just a super-fast, super-powerful calculator.

As simple as that may sound,keep in mind that a CPU churns out billions of

calculations every second. These calculations make possible everything that

your PC does: displaying your operating system (OS) desktop, processing

print jobs, grabbing Web pages, and doing everything else that you ask it to do.

Of all the whiz-bang pieces of engineering that go into the PC, the CPU is by

far the most impressive. The CPU has gone through many evolutions since its

introduction more than 20 years ago, but even the most advanced CPUs still

operate in much the same manner as the old Intel 8088 that powered the first

IBM PC.

Today’s desktop CPU market is dominated by two vendors, Intel and Ameri-

can Micro Devices (AMD). Intel’s CPU offerings include the Pentium, Celeron,

Core, Core 2, Xeon, and Itanium processors. AMD gives us the Athlon XP,

Sempron, Turion, and Athlon 64 product families, and the server-oriented

Opteron processor.

Travel Advisory

Over the years, other companies have tried to get into the CPU

business. Companies such as Cyrix, IDC, VIA, and Transmeta have

all made CPUs, but they’ve been met with limited success and

minor market share.

The CompTIA A+ certification exams concentrate on the aspects of the CPU

that a tech has to know to service PCs in today’s business world. First, you need

to understand the basic internal components of a CPU and what they do so that

you can make informed decisions and recommendations on CPUs. Second, you

need to know how to install a CPU and its cooling system. Finally, you need to

handle the relatively simple troubleshooting CPUs require.
