Power Supply, Motherboard, &
Microprocessors
TERM DEFINITONS
Bay Opening in the computer cabinet used for the
installation of electrical equipment.
Power Supply This converts AC to DC to run the
computer.
Surge Protector Protects the computer from being
damaged by power spikes. Plug your computer into one.
UPS Uninterruptible Power Supply. Battery-operated device
that provides power for a limited time when there is a blackout.
Motherboard Main
system board of the computer (also systemboard).
Microprocessor Miniaturized
circuitry of a computer processor.
Chipset Groups of interconnected chips on
the motherboard that control information flow between the microprocessor and
other system components connected to the motherboard.
One View Of a Motherboard
Another View of a Motherboard
•Traditional microcomputer
microprocessors are Intel
and AMD.
•Multicore processors (2, 4, 6, 8) have more than one
processor “core” on a
single silicon chip, which
allows computers to run faster.
•Special processors are made for portable
devices.
• A
graphics processing unit (GPU) is a specialized processor
used to manipulate three-dimensional (3-D) computer graphics.
Processing Speeds
•Every microprocessor contains a system clock, which
controls how fast all the
operations within a computer take place
(the chip’s processing speed).
•Older CPU processing speeds are in megahertz.
•1 MHz
= 1 million cycles per second
•Current CPU processing speeds are in gigahertz.
•1 GHz
= 1 billion cycles per second
•The faster a CPU runs, the more power it
consumes, and the more heat it generates.
