Input/Output Device


    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 br 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 capabilit to perform airthmatic operations character manipulation operations and logocal operations.The output unit display the computer results.It possible to develop enormous number of different interesting patterns bny prmuting and combining a few basic types of instuctions.The same principle is used in building computers.Thus by using a computers processing unit which can interpret and execute as few s ten different operations,it is possible to perform a large variety of data processing tasks.
