write the three stages of Computing. Explain with the help of a diagram?
Answers
Answer:
The three stages of computing are input, processing and output. A computer works through these stages by 'running' a program. A program is a set of step-by-step instructions which tells the computer exactly what to do with input in order to produce the required output.
Explanation:
The three stages of computing are input, processing and output.
A computer works through these stages by ‘running’ a program. A program is a set of step-by-step instructions which tells the computer exactly what to do with input in order to produce the required output.
Input
This stage of computing is concerned with getting the data needed by the program into the computer.
Input devices are used to do this.
The most commonly used input devices are the mouse and the keyboard.
Processing
The instructions about what to do with the input are contained in a program.
During the processing stage the computer follows these instructions using the data which has just been input.
What the computer produces at the end of this stage is called output.
Output
This stage of computing is concerned with producing the processed data as information in a form that is useful to the user.
Output devices are used to do this.
The most commonly used output devices are the screen, which is also called a monitor or visual display unit (VDU) and the printer.
