| PCI |
| |
|
A bus developed by Intel
that supplants the ISA bus as
the standard for expansion cards. The PCI bus allows you to
add up to nine expansion cards, but this number is usually
reduced by motherboard manufacturers due to size and cost
issues. The PCI bus is superior to the ISA bus in that it
can transfer data at a much faster rate and is less prone
to device conflicts.

| POWER
SUPPLY |

|
The Power supply is the part of the
computer that converts the power from an electric socket into
electricity suitable for use by the computer. It is usually
rated at 150 watts at the low end to over 300 watts at the
higher end. The Power supply is a major source of heat and
usually needs an auxiliary ventilation source such as a fan
to keep it from damaging other components in the computer
system. The power supply usually is bundled with the computer
case.
