Input/ Output systems are used in the computers. There are many components of the computer which serves as the input for the computer system and output for the computer system. There are different inputs of the computer system like mouse, keyboard, storage devices, CD Rom and light pen so these serve as the input in the computer system. The data is being input in the computer for the different types of the devices in order to give the opportunity to the system so that you can process it through the processor.
