Why you need interfacing devices in microprocessor?

Answer 1

microprocessor is a programmable chip that serves the purpose of several components working as a system on the PCB. the ports of the microprocessor are used to simultaneously provide the data and address. it was the basic building block of the third generation computers that makes them compact and versatile. the further advancements in this field makes the communication equipments steek. that shows the need of microprocessor .

Answer 2

A microprocessor can perform various functions depending on how you connect them up to other hardware.

An interface device is like a two-way street. Interface devices are always connected as something that you would do (input) that triggers a result (output).

For example, your computer's microprocessor can still perform without a keyboard or screen. Then what's the point? The keyboard acts as the input (you typing) and the screen is the output, which you can read. So without interface devices, microprocessors are much more boring than usual, even though they can still run perfectly fine.

Answer 3

the principle function of memory interfacing is to enable the microprocessor to read or write into a register of the memory chip
