The CPU is constantly following instructions of computer programs that tell it which data to process and how to process it.

Detailed explanation-5: -Like input devices, output devices are attached to a CPU by way of a “peripheral IC.” Depending on the kind of output device to be connected to the CPU, an appropriate peripheral IC is used. Input devices and output devices are collectively called “peripherals."
