computer ,input and output device sof computer

What is computer list some input and output devices of compueter.

Expert Solution

computer is a programmable digital electronic device which can accept data as input from the user processess the data and provides the desired output i.e information to the user.

computer performs five basic functions which are as listed below

Input:Information or data that is entered into a computer is calle input.The input section sends data and instructions to the central processing unit of computer

Processing: Sequence of actions taken on data to convert it into information which is meaning to user.It can be comparisions, calculations or decisions taken by the computer.

output: It makes processed data available to the user,it is mainly used to display the desired result to the user as per input instructions

storage: It stores data and programs permanently.It is used to store information during the time of program execution and possible to get any type of information from it.

controlling: controlling of all the above functions of computer is controlled by controlling section.

Input devices are those devices which can accept data as input from the user,while ouput devices are those devices which which sends the proceesesd data to the user.

There are some input and output devices of the user as listed below.

input devices output devices

keyboard Monitor

Mouse Speaker

Trackball Printer

Joystick Plotter

Light pen Projector

Touch screen etc

Barcode Reader

Optical Mark reader

Optical character recognition

Magnetic ink character reader

Biometric sensor

Scanner

Microphone

webcam

etc

Touch sceen acts as both input and output device

computer is also known as data processor.

computer is not an intelligent device.

Course: Computer Architecture (Theme: Input-Output) A computer consists of a processor and an I/O device D connected to main memory M via a shared bus with a data bus width of one word. The processor can execute a max of 2 MIPS. An average instruction requires 5 machine cycles, 3 of which use the memory bus. A memory read/write operation uses 1 m/c cycle. Suppose that the processor is continuously executing “background” programs that require 96% of the instruction rate...
