2. What is a power supply?
A power supply is a device that
supplies electrical energy to one or
more electric loads.
Every power supply must obtain the
energy it supplies to its load, as well as
any energy it consumes while
performing that task, from an energy
source.
Why is a power supply useful?
The power supply in your PC provides all of the different voltages
your computer needs to operate properly. Power supply adaptor.
It helps the computer to get as much power as it needs.
3. Hard drive
A hard drive is a hard disk drive that is a non-volatile, random
access digital magnetic data storage device. It features
rotating rigid platters on a motor-driven spindle with in a
protective enclosure. Introduced by IBM in 1956, hard disk
drives have decreased in cost and physical size over the years
while dramatically increasing in capacity.

4. The expansion card in computing is a printed circuit board that can
be inserted into an expansion slot of a computer motherboard or
backplane to add functionality. One edge of the expansion card
holds the contacts that fit exactly into the slot. They establish the
electrical contact between the electronics on the card and on the
motherboard.
Connectors mounted on
the bracket allow the
connection of external
devices to the card.
Depending on the form
factor of the motherboard
and case, around one to
seven expansion cards can
be added to a computer
system. 19 or more
expansion cards can be
installed in backplane
systems. There are also
other factors involved in
expansion card capacity.
5. An expansion slot is a expansion port alternatively referred, an
expansion slot is a computer which is located on the
motherboard or on the riser board that allows additional to be
connected to it. Below is a listing of some of the expansion slots
commonly found in IBM compatible computers as well as other
brands of computers and graphic illustration of a motherboard
and its expansion slots.
6. In personal
computers, a motherboard is
the central printed circuit
board (PCB) in many
modern computers and holds
many of the crucial
components of the
system, providing connectors
for other peripherals. The
motherboard is sometimes
alternatively known as the main
board, system
board, or, on Apple computers,
the logic board. One of the
most important components of
the PC's base plate. The
quality, the better they work
other components. On the
market there are many
manufacturers base.
7. CD-ROM drives are necessary today for
most programs. A single CD can store up
to 650 MB. Of course, it’s nice to have the
little bits of extra speed. However, when
you consider CD-ROM drives are
generally used just to install a program.
The extra speed isn't usually very important.
The speed can play a big role.
A CD-ROM drive, an acronym of "Compact
Disc Read-only memory drive") is a pre-
pressed compact disc that
contains data accessible to, but not writable
by, a computer for data storage and music
playback. The 1985 “Yellow Book” standard
developed by Sony and Philips adapted the
format to hold any form of binary data.
8. A DVD is an optical disc storage media
format, invented and developed
by Philips, Sony, Toshiba, and Panasonic in
1995. DVDs offer higher storage capacity
than Compact Discs while having the same
dimensions.
Pre-recorded DVDs are mass-produced
using molding machines that physically
stamp data onto the DVD. Such discs are
known as DVD-ROM, because data can only
be read and not written nor erased.
DVDs are used in DVD-
Video consumer digital
video format and
in DVD-
Audio consumer digital
audio format, as well as
for authoring AVCHD
discs.
9. RAM ( in English random-access
memory , random access memory) is
the science type of electronic memory ,
which allows access to any part in
constant time, regardless of its
physical location (as opposed to
sequential memory, such as magnetic
tape , optical disc or hard drive ).
Types of RAM
DDR2 RAM Windows XP
Windows Vista
Windows 7
Corsair
DDR3
Intel Socket LGA1366
DIMM AMD Phenom II
10. Processor ( English Central Processing Unit , an
abbreviation of the CPU ) in computer science an essential
part of a computer that performs machine
code running computer program . It is composed of
individual machine instructions that are stored
in memory computers. The processor is currently very
complex sequential integrated circuit located on the
motherboard your computer.
11. A power supply is a device that supplies electrical energy to
one or more electric loads. A CPU in computer science is an
essential part of a computer. RAM is the science type
of electronic memory. A DVD-ROM is an optical
disc storage media format, a CD-ROM drives are necessary
today for most programs. A hard drive is a hard disk drive that
is a non-volatile, random access digital magnetic data storage
device. The expansion card in computing is a printed circuit
board. An expansion slot is a slot located inside a computer on
the motherboard or riser board that allows additional boards
to be connected to it. In personal computers, a motherboard is
