All About Computers

Five Basic Parts of Computer
•Inputting: The Process of entering data and instructions into the computer system

•Storing: Saving data and instructions to make them readily available for initial or additional processing whenever required.

•Processing: Performing arithmetic operations(add, subtract, multiply, divide, etc.) or logical operations(comparisons like equal to, less than, greater than, etc.) on data to convert them into useful information.

•Outputting: The process of producing useful information or results for the user such as a printed report or visual display

•

•Controlling: Directing the manner and sequence in which all of the above operations are performed

All input unit of a computer system performs the following functions:

1.It accepts(or reads) instructions and data from outside world

2.It converts these instructions and data in computer acceptable form

3.It supplies the converted instructions and data to the computer system for further processing

An output unit of a computer system performs the following functions:

1.It accepts the results produced by the computer, which are in coded form and hence, cannot be easily understood by us

2.It converts these coded results to human acceptable(readable) form

3.It supplies the converted results to outside world
