First i am explain the three basic function of sytsem
at last with a simple example i am explain how the basic
function works on a computer system
three basic functions of system
Input
- Data and Instructions which we give to the computer are known
as input
- eg: keyboard, mouse, etc
Process
- Work done on data according to the given instruction is known
as processing
- eg: CPU (Central Processing Unit) is the brain of the computer.
all data and instruction which are given to the computer is
processed within the CPU
- It stores all the data, intermediate results, and instructions
as given by the programmer in the form of codes.
Output
- processed data is knows as output .Output is the function that
allows a computer to display information, from the system, for the
user.
- eg: Monitor,Printer,Speaker etc..
How Basic
Function Works On a System with a simple
Example
- eg: with a simple example below explain how the basic function
of compter system works
- Suppose when we add two numbers 4 and 5 on a computer
system
- 4+5
our input will be two numbers 4 and 5
Processing is the addition (+) of two
numbers
Finally our output is 9 addition of two
numbers
