Q. What is microcomputer system?
The microcomputer has a single microprocessor and a number of RAM and ROM chips as well as an interface unit which communicates with several external devices via the I/O Bus.
Input/Output subsystem of a computer referred to as I/O offers an resourceful mode of communication between central system and output environment. External devices which are under direct control of computers are said to be connected on-line. These devices are created to read information into or out of memory unit upon command from CPU and are determined to be part of computer system. I/O devices attached to computer are also known as peripherals. We can roughly classify external devices or peripherals in 3 categories:
