CONTENTS

A body of knowledge devoted to creating tools, processing actions.

An application of science to solve a problem.

Technology is dynamic.

TECHNOLOGY

( Commonly Operated Machine Particularly Used for Technology , Education and Research)

Charles Babbage designed the first mechanical computer in 1822, it was called Analytical Engine. 

COMPUTER

Printer

WebcamCPU

MoniterS.box

KeyboardMouse

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.

COMPUTER PERIPHERAL

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.

Type s of peripheral

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

LIST OF COMPUTER PERIPHERAL DEVICES

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)

Some imp. Computer peripheral devices and their uses :-

Keyboard:-

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.

CRT Monitor LCD Monitor

VGA ports and connector

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.

3.HARD DRIVE:-

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 )

What are not Comp. Peripheral ?

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.

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.
