Compare between INPUT and OUTPUT devices and Discuss the process involve in getting data into the computer.
Input is the data that you put into the computer system for processing whereas a output device make computer hardware information into human readable form.
It can be anything like text, graphics, audio, and video. Actually An input devices sends information to a computer system for processing, and an output devices reproduces or displays the results of that processing. Input devices only allow for input of data to a computer and output devices only receive the output of data from another device.
A input devices can send data to another device, but it cannot receive data from another device. Here is some example: Keyboard, Mouse, Webcam, Microphone.
An output device can receive data from another device and generate output with that data, but it cannot send data to another device. Monitor, projector, speakers are the best example foe OUTPUT devices.
Data processing is actually who make raw data to meaningful information trough a process.
Data is processed by mechanical or automated means. Note that processing of data may take time depending on the complexity of the data and the volume of input data.
