Q. Structure of Input - Output Interface?

Due to complexity and number of external devices that I/O interface control, there is not any standard structure of I/O interface. Let's give a general structure to an I/O interfaces:

  • There is a requirement of I/O logic that must interpret and execute dialogue between processor and I/O interface. Thus there need to be control lines between I/O interface and processors.
  • Data line associating I/O interface to system bus should exist. These lines serve purpose of data transfer.
  • Data registers may behave as buffer between I/O interface and processor.
  • The I/O interface comprises logic specific to interface with every device that it controls.
