this presentation was presented in our Educational Technology 2 subjects and demonstrated this. the title is Parts of the computer and their function. This presentation also include activities. just also check the hyperlinks on the presentation.
9. Major Parts of the
Computer
CPU
RAM
Hard Drive
Optical Drive
Motherboard
10. Central Processing Unit (CPU)
The central processing unit (CPU) processes
all of the data that is accessed by the
machine. It is a small internal piece that is
located beneath the fan. Essentially, the
purpose of a CPU is to process instructions
through a four-part sequence of
fetching, decoding, execution and write-back.
11. Random access memory provides a
buffer between the hard drive and
central processing unit. When files are
requested for processing, they transfer
from the hard drive to the memory.
12. • A hard drive provides
permanent storage for
the operating system,
programs and files on a
machine. When files are
saved to the hard drive,
they are retained through
power outages.
13. An optical drive is any drive that reads
the data through optic
technology, such as a laser. These drives
can read data from discs.
14. Motherboard
The motherboard is an underlying circuit
board that holds all the computer
components together. Computer
components, including the
CPU, RAM, hard drive and optical
drives, plug into the motherboard. This
allows the separate components to
interact with each other to create a fully
functional machine. While each computer
part has a unique function, they would be
utterly useless without the unifying
motherboard.

16. Different Equipment of the
Computer
Desktop
Monitor
USB flash drive
Mouse
Speakers
Headphones
Microphone
Hub
Printer
Scanner
Keyboard
20. A hand-held input
device you roll on
your desk to point
to and select items
on your screen.
When you move the
mouse, the mouse
pointer on the
screen moves in the
same direction.
23. Input device in
which sound
energy is changed
into electrical
energy for the
sending or
recording sound
(your voice).
24. Hubs are devices that have
many ports into which
network cables are plugged.
A hub takes the signal from
each computer and sends it
to all of the other
computers through the
network.
25. A device that produces a
paper copy of the information on your
screen.
26. Output device for displaying onto a
large surface (projection screen) what
appears on the computer monitor.
28. The keyboard is an input
device designed to enter
text, characters and other commands
into a computer or similar device.
29. Manipulate a Computer
• Point the icon of the “computer”
and open it.
• Plug the speaker to the
computer and demonstrate the
function of the speaker.
• Connect the projector to the
computer.
• Point a video, open it, plug the
speaker and project it in the
