The I/O interface provides a technique for transferring information between external I/O devices and internal storage. Peripherals linked to a computer require special communication links for interfacing them with CPU. Objective of communication link is to resolve differences which exist between central computer and every peripheral. The key differences are:
To resolve these differences, computer systems include special hardware component between the CPU and peripherals to supervise and synchronize all input and output transfers. These components are called interface units because they interface between the processor bus and the peripheral device.
