INPUT/OUTPUT DEVICES

Input/Output Units: A computing machine designed to carry out algorithms for data processing thus has the seen input unit is provided to read the algorithm and data to be processed by the algorithm. The memory unit stores the algorithm and computed values. The processing unit interprets the instructions and carries them out. It has the capability to perform arithmetic operations character manipulation operations and logical operations. The output unit displays the computer results. It is possible to develop an enormous number of different interesting patterns by permuting and combining a few basic types of instructions. The same principle is used in building computers. Thus by using a computer processing unit that can interpret and execute as few s ten different operations, it is possible to perform a large variety of data processing tasks.
