The document discusses computer peripherals. It defines peripherals as devices connected to but not part of the core computer architecture that are used to input or output data. It lists common peripherals like keyboards, mice, monitors, printers and storage devices. It categorizes peripherals as input, output or storage and provides examples and uses of important peripheral types like keyboards, monitors and hard drives. It also discusses advantages and disadvantages of some peripherals.

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.
