MICRO PROCESSOR is a silicon chip that contains central processing unit.Micro processor controls every action in a computer or in a electronic device.It is a multipurpose, programmable device that accepts digital data as input and processes it according to instructions stored in its memory and provides results as output.
Micro processors also controls the logic of almost all digital devices, from clock radios to fuel-injection systems for the automobiles.General purposes of micro processors are in personal computers which are used for computation,text editing,multimedia display and communication over internet.And many more micro processors are a part of embedded systems providing digital control of a object from appliances of automobiles to cellular phones.

Micro processors has replaced the integrated circuits,huge transistors and transformed as a modern technology unit.The first developed micro processor was 'INTEL 4004' in early 1970's and were used for electronic calculators,using binary-coded decimal arithmetic on 4-bit word.There are 4-bit and 8-bit micro processors such as terminals,printers,various kinds of automation etc.And then came the 16-bit micro processor for more advance use in that period itself which runs at 25MHz.Presently we are also using the 32 bit micro processor which runs at 50MHz.nowadays in every electronic device the micro processors are emerged which doesn't occupies much space.
