• What is “Computer Interfacing” ?

,Introduction
• Computer Interfacing handles how to connect peripherals to a
computer system
• Interfacing includes how to integrate and communicate with other
devices outside the computer system
• Computer Interfacing is a mixture of hardware and software
knowledge !

, Introduction
• Interfacing mainly looks at how to exchange data between a
processor and external peripherals
• Interfacing includes designing hardware circuits to connect the
external hardware with the processor
• It also includes designing software handlers that perform the
communication with the peripherals
• Understanding the behavior of the peripheral is necessary to desig
proper interface for it
