Answers
Answer:
The process of a computer task can be divided into three stages:
Input
Process
Output
Input-Process-Output cycle
Input means to put in or into and that is exactly what an input device does. An input device enables one to communicate with the computer. Input devices are used to enter information and issue commands. Examples of input devices are the keyboard, mouse, scanners, video cameras and microphones.
Information received from the input devices will then be processed in the Central Processing Unit (CPU). The CPU's job is to process instructions, perform calculations and manage the flow of information through a computer system. The CPU not only communicates with the input devices, but also the output and storage devices to perform tasks.
After the information has been processed, or the necessary tasks completed on the information, it will be outputted to you. The output device enables a computer to communicate with you. These devices display information on a screen, create printed copies or generate sound. Some of these devices are the monitor, printer and speakers.
