It is a program controlled semiconductor device (IC}, which fetches, decode and executes instructions.

The basic units or blocks of a microprocessor are ALU, an array of registers and control unit.

The Software is a set of instructions or commands needed for performing a specific task by a programmable device or a computing machine.

The Hardware refers to the components or devices used to form computing machine in which the software can be run and tested. Without software the Hardware is an idle machine

The language in which the mnemonics (short -hand instructions) are used to write a program is called assembly language the manufacturers of microprocessor give the mnemonics.

The software developed using 1’s and 0’s are called machine language, programs. The software developed using mnemonics are called assembly language programs.
