A computer system consists of mainly four basic units; namely input unit‚ storage unit‚ central processing unit and output unit. Central Processing unit further includes Arithmetic logic unit and control unit‚ as shown in the figure:. A computer performs five major operations or functions irrespective of its size and make. These are • it accepts data or instructions as input‚ • it stores data and instruction • it processes data as per the instructions‚ • it controls all operations inside a computer
