2.  Introduction
 What is Computer Peripheral
 Types of Computer Peripheral
 Some Imp. Peripheral devices and their uses
 What are not Computer Peripheral
 Advantages and Disadvantages
 Conclusion
 References

3.  A body of knowledge devoted to creating tools,
processing actions.
 An application of science to solve a problem.
 Technology is dynamic.

4. ( Commonly Operated Machine Particularly
Used for Technology , Education and Research)
 Charles Babbage designed the first mechanical
computer in 1822, it was called Analytical
Engine.

5. Printer
Webcam
CPU
Moniter
S.box
Keyboard
Mouse

6.  Devices that are connected to the computer,
but is not a part of core computer architecture.
 Device that is used to put information into or
get information out of the computer.

7.  1.Input devices - Used to interact with , or send
data to the computer. Ex- Mouse , Keyboard etc.
 2.Output devices - Provide output to the user
from the computer. Ex-Monitor , Printer etc.
 3.Storage devices - Store data processed by
computer. Ex-Hard drives , Flash drive etc.

8.  INPUT
 Keyboard
 Mouse
 Touchpad
 Touchscreen
Monitor
 Joystick
 Scanner
 OUTPUT
 Monitor( LCD,
CRT etc)
 Printers
 Projector.
 Speaker
 Head Phone.
 STORAGE
 Hard drives
 Flash drive
 Recording tape

9.  1. KEYBOARD :-
 Made up of push button switches which send a signal to the
CPU each time we press them.
 Having alphabet, numbers, function ,special keys.
 Software keyboard or on screen keyboard display an image of
a keyboard on the screen.
 The AT keyboard is a keyboard with 84 keys, It was later
replaced with the 101-key .
 It can be used for shortcuts ,helpful in DOS command (where
mouse doesn’t work)

11.  2.MONITOR:-
 An electronic visual display for computers.
 Technology used for computer monitor:-
1.CRT 2. LCD etc.
 The first computer monitor used cathode ray tubes (CRTs).
 The first desktop LCD computer monitors was the Eizo L66
in the mid-1990s.
 Present in many aspect ratio (width:height) in market.

12. CRT Monitor LCD Monitor
VGA ports and connector

13.  Introduced in 1956 for an IBM computer.
 It is used to store data for long time (Permanent storage). Data
can include the computer's operating system and applications
as well as personal files including photographs, documents
and music.
 2 types of Hard drive:-1.HDD-Hard disc drive(Magnetic disc)
2.SDD-Solid state drive
 Each computer have a Hard drive.

15.  1.Power Supply Unit
 2.Motherboard
 3.C.P.U.
 4.R.A.M.
 Computer Case
(The devices that without which a computer
can not process , even a single task )

17.  ADVANTAGES
 1.JOYSTICK:-Easy to learn
to use.
 2.REMOTE CONTROL:-
Each function can have its
own button making them
very simple to use.
 3. DIGITAL CAMERA:-
No film is needed and
unwanted images can be
deleted straight away.
 4.HEADPHONE:- Easy to
use and keep.
 5.STORAGE DEVICE:-
Very fast to access the data
and cheap to buy.
 DISADVANTAGES
 1. Directions in simple
joysticks are limited
 2. They cannot be used to
control anything other than
the device they were
designed for.
 3. Images often have to be
compressed to avoid using
up too much expensive.
 4.It required digital sound
signal to convert.
 5.Saved data are deleted ,if
device fails.

18.  A peripheral device is generally any auxiliary
device that connects to and works with the computer
to increase functionality of computer.
 Peripheral devices can be input/output, external or
internal. Some devices, such as video display
terminals, may provide both input and output.
