You will see a big metal box with a
fan on it. That's the power supply.
It takes house current (110 volts,
alternating) and steps it down to
5 and 12 volts direct current, to
supply the computer's needs.
You will see the disk drives.
You will also see some large
printed circuit boards that plug
into long sockets on an even bigger

expansion cards.
The motherboard contains the most
essential parts of a computer, the
Central Processing Unit, called CPU,
the RAM and ROM memory, and an
assortment of other important parts.
The expansion boards contain special
circuits for "accessories" such as
your monitor, disk drives, and
options you might have such as a
mouse or modem.
