1. Motherboard
A motherboard
looks like this.
The mother board is the
centre part of the
Computer.
It holds the
Components and connects them together with a
series of circuits and chips . This is also helps power
each component

2. Hard drive(HDD)
• Hard drive is a very important Component.
• The hard drive stores most of the computers
information including the operating system and
all of your programs.
• Almost all computers have one or more.

3. case
• The computer's case hold all the components
• It has a USB Port and disk drive
• They sometimes have built in fans

4. Sound card
• The sound card is the main component for
sound also know as the audio card
• The input and output of audio signals to and
from a computer under control of the
computer programs.
• Most sound cards are integrated into the
motherboard with the video card

5. Disk drive
• A disk drive is a optical drive that
reads compact disks like DVDs and
CD
• The drive uses a laser light to read the
information on the disc

6. CPU (Central processing unit)
• The Central processing unit carries out the
instructions of a computer program, it performs the
basic input/output operations of the system.
• The power of a CPU is currently measured
In gigahertz (GHz) and are 64-bit
it ran faster
• Newer CPUs use multi cores, this means
There is more then one chip inside the processer

7. Graphics card
• The graphics card gives a video output to the
monitor
• They mostly use PCI,PCIe
and AGP slots to fit into
the motherboard but
most modern graphic cards are integrated into the
motherboard
• They use HDMI,DVI and VGA ports to connect to
the visual display device

8. Heat sink
• The heat sink cools the computer down so it
does not over heat
• It removes waste heat made by computer
components
• It keeps components within their safe
operating temperature

9. Heat extractor
• The heat extractor is for getting rid of waste
heat so the CPU will not melt or crash

10. Power supply
• The power supply in the computer provides all
of the different voltages your computer needs
to operate properly
• It converts AC voltage
from the mains into DC
voltage

11. RAM (random access memory)
• RAM is for running and loading applications
• RAM is also used for advance gaming and
graphics software
• It also a temporary storage device for
computer data

12. firewire
• FireWire is a method of transferring
information between digital devices,
especially audio and video equipment
• Firewire is 400 MB/s or 800 MB/s
• Not many peripherals use firewire, it is mainly
used for cameras and camera recorders

13. Sata cable
• The sata cable has seven conductors, one
keyed connector for the drive, and one keyed
connector the drive controller.
