Question

A seminar paper for computer peripherals

1-input devices

2-output devices

3- storage devices

Answer 1

Hi,

Computer peripherals:  
Devices those are connected to computer but those not part core compute architecture are called as Computers Peripherals.
Those devices may used to put information into computer(input), or get information from computer(output), or may used to store information externally(storage).
--> Computer peripherals broadly dived into 3 categories:
1. Input devices : Used to interact with, send data to computer. Example : Mouse, Keyboard etc.
2. Output devices : Provides output to the user from computer. Example : Monitor, Printer etc.
3. Storage devices : Store data processed by computer. Example :Hard drives, Flash drives etc.

List of computer peripheral devices:

Input Devices	Output Devices	Storage Devices
Keyboard	Monitor(Lcd, crt etc)	Hard drives
Mouse	Printer	Flash drives
Touchpad	Projector	Recording tapes
Touchscreen Monitor	Speaker	-
Joystick	Head phone	-
Scanner	-	-

Some important computer peripheral device :
1. Keyboard (input):
--> 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)

2. Monitor (output):
--> 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.

3. Hard Drive (storage):
--> 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.

Conclusion :

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.
