In terms of your desktop
components, CPUs are the "brains" of computers. This is
where the system gets the go-ahead for all of the processes
in which you are engaging. Although other parts of the
system can dictate your system's speed, it's the computer
processor that is the ultimate arbiter of what you can do
with your system.
The CPU is also called the "processor"
or "microprocessor." Almost all processors are
microprocessors these days, so the names are virtually
interchangeable. The reason they are called "micro"processors
is because all of the data is contained in a tiny chip.
Despite the small size of these chips, every 18 months or
so, the amount of information they can hold and transfer
increases dramatically.
Processors offer speeds of multiple GHz now, more than
many computer users need. If you do a lot of video editing
or play some of the more advanced games, you may benefit
from these extreme speeds. Otherwise, you will just end up
paying for more speed than you really need. However, always
be sure to check your favorite software for system
requirements; you don't want to invest in software that your
system can't handle.
The microprocessor superstars, Intel and AMD, make
microprocessors in a number of speeds and prices. For
instance, Intel makes the Pentium 4 and the Celeron (as well
as an Extreme Pentium 4, their fastest). For price-conscious
consumers, the family of Intel processors includes the
Celeron, which offers enough speed for average computer use
at a lower cost than the super-speedy Pentium 4. Those
shopping for price may also want to consider an AMD
processor. Look at the programs you want to use, then choose
your CPU (and RAM!) accordingly.
