I.C.s can do many things. Some are
R.O.M. chips. These are Read Only
Memory. Memory of this sort is like
a newspaper. You can read it as
often as you like, but you can't
change it.

Others are R.A.M. chips. RAM
stands for Random Access Memory.
These chips can be told something and
will remember it. If you tell them
something different, they will then
remember the new information. They
only work when the power is on. If
you turn the computer off, the RAM
chips forget everything.

Other chips can make decisions.
Their individual thinking power is
limited, but they team up to control
the operation of your computer.

There is one special I.C.
chip called the C.P.U., which
stands for Central Processing
Unit. It is often the largest
bug in the box, with the most
legs. Almost every bit of
information the computer
handles is controlled by this
chip. Intel is the most famous
manufacturer of CPUs for
IBM-compatible computers. In
PC-class machines the Intel CPU
model number is 8088. In XT
computers it is 8088-2. In
AT-class machines it is 80286,
in '386' computers it is number
80386 and in '486s'... you
guessed it. (80486)
