WORKING OF A COMPUTER
As we have discussed earlier, a computer can do a lot of things. Let us understand
how a computer works.
A computer works in three steps: Input Process Output (IPO). This is also
called the IPO cycle.
Input Process Output
INPUT
We enter data and instructions into the computer which is called input. The devices
which are used to send input to a computer are called input devices.
PROCESS
A computer works on data (input) to produce meaningful information with the help of
processing device known as the CPU (Central Processing Unit). This conversion of
data into information is called processing. CPU is also called the brain of a computer.
