The document outlines the common components of a computer system including the CPU, HDD, RAM, power supply, expansion cards, optical disc drive, and motherboard. The CPU processes all calculations and functions, the HDD reads and writes data to the hard disk, RAM provides random access memory, the power supply provides power, expansion cards enhance capabilities, the optical disc drive reads and writes optical discs using lasers, and the motherboard connects the main computer components.

2. CPU (central processor unit)
• A CPU is the brains of the
computer that send
functions to the rest of the
components. CPU is were all
calculations are made in
terms of computer power.
Without a CPU the
computer will not function

3. HDD (hard disk drive)
• The HDD Is a mechanism
that is able to read and
then writes data on a hard
disk . Hard disk’s are
generally for Pc’s . There
seek times are generally
12 millie seconds or less.
HDD can improve through
a technique called
caching.

4. RAM (random access memory)
• RAM stands for random
access memory. This sort
of memory can be
accessible randomly,
which is any byte of
memory that can be
accessed without touching
the preceding bytes. RAM
is the most common type
of memory in most
computer or other devices
such as printers.

5. Power Supply
• The power supply is where
the computer receives the
source of energy for it to
turn on.

6. Expansion card
• A expansion card is a card
that can be inserted into
the computer to give it
added capabilities, which
will enhance he
performance.
• Examples of expansion
cards:
• Video adapters
• Graphic acceleration
• Sound card
• Internal modems

7. Optical disc drive
• A optical disc drive is a
disk drive that functions
by using a laser light or an
electromagnetic waves.
This process reads the
data . Some drives only
read disks. On the other
hand common once read
and record. Common
types of optical drives are:
• DVD PLAYERS
• BLU-RAY DISCS

8. Motherboard
• A motherboard is
were all the main
parts of the
computer is
mounted on.
