2. 20+4 pin ATX main power cable POWER SUPPLY
UNIT is also called as
power supply or PSU.
This is the device that
supplies power to your
personal computer.
Although you could
plug the personal
computers directly into
standard electrical
outlets, the power
supply then pulls the
required amount of
electricity and converts
the AC current to DC
current and it also
regulates the voltage
to eliminate spikes and
surges common in
most electrical
systems.

6. Floppy drive power cable

12. BEFORE APPLYING POWER, ENSURE VOLTAGE SELECTION SWITCH
ON THE POWER SUPPLY IS SET CORRECTLY!

14. Hard Disk Drive (HDD) is also known as hard drive. This is the computer's
main storage device used to store all data on the computer permanently.
Commonly, hard drives are permanently place in an internal drive bay at the
front of the system case and are connected with either P-ATA or a S-ATA cable
and power cable. Some Hard drives nowadays are portable which use USB
ports and USB cable for connection.

17. The larger your HDD capacity the better but the
higher the price it could be. Choosing a Hard Drive
is relatively simple and is usually based of 2 factors,
size and speed. The size of the drive you choose
will be primarily based on your personal needs, but
for most people a drive not less than 160GB is a
good starting point. Example:
MAXTOR / IDE / 160 GB - 1200
MAXTOR / S-ATA / 250 GB - 1400
MAXTOR /S-ATA / 500 GB - 2500

19. OPTICAL DISK DRIVE is a device that uses photo diodes to detect
reflecting lights on optic discs and uses a laser to read or write
data. Commonly, it uses the same cables as hard drives to
connect to the motherboard.
CD DRIVE – COMPACT DISC
CD RW DRIVE - COMPACT DISC RE-WRITABLE DRIVE
DVD DRIVE - DIGITAL VERSATILE DISC
DVD –RW DRIVE- DIGITAL VERSATILE DISC RE-WRITABLE DISC.

20. IDE/P-ATA (Ultra ATA 100) Cable S-ATA Cable
PATA (Parallel ATA) and SATA (Serial ATA) ports are used for the connection of
hard drives and optical drives.
ATA is the acronym for Advanced Technology Attachment.
ATA is also known as IDE or EIDE (Enhanced Integrated Drive Electronics).

21. SDRAM (Synchronous DRAM)
DDR (Double Data Rate SDRAM)
RANDOM ACCESS MEMORY: The personal computer memory module also known
as Random Access Memory (RAM) is a piece of hardware that allows stored data to
be accessed randomly. Its main function is to store the data temporarily.

CENTRAL PROCESSING UNIT: The CPU, or the Central Processing Unit, is
the brain of the computer and one of the most important chip in the computer.

23. Below are the major socket types for contemporary AMD motherboards:
Socket 754 Socket 939 Socket AM2
Important Information:
Current Socket 754 processors include the Sempron series and older model Athlon 64
processors. Some AMD K8 desktop processors such as the Athlon 64, Athlon 64 FX,
and Athlon 64 X2 utilize the Socket 939 socket. The latest Socket AM2 has been
adopted by all AMD desktop processor families including Sempron, Athlon 64, Athlon 64
FX and Athlon 64 X2.

24. EXPANSION CARD is also
known as Also known as an add-
on card, internal card or
interface adapter or interface
card. Expansion card is an
electronic board or card added in
a personal computer so the
computer will have a new
functions.

25. VIDEO CARD is commonly known as graphics
accelerator card, display adapter, or graphics card.
This is a hardware component whose main function
is to generate and display the output images to a
computer monitor.
TYPES:
