Programming with Assembly Language

A Microcomputer is a mini-computer. It is an electronic machine that has the capability of performing complex tasks within fraction of time. It can store large volumes of data, process it, compile it and manipulate it at much faster rate. A microcomputer is the composed to of a microprocessor and peripheral I/O devices. These devices communicate and operate in terms of two binary values '0' and '1' known as binary digits or bits. The bit size of a processor denotes the number of bits that a microprocessor can process. A group of such bits form a word. The microprocessors are classified in terms of word size they can process, for example Intel 8085A is an 8-bit microprocessor and Intel 8086 is a 16-bit microprocessor.
