Computer is an advanced electronic device that takes raw data as input from the
user and processes these data under the control of set of instructions (called

process both numerical and non-numerical (Arithmetic and Logical) calculations. It
works the principle of I-P-O Cycle.
A computer has four functions:

 processes data Processing
 produces output output
 stores results Storage
