PROCESSORS

HISTORY OF MICRO PROCESSORS 

  Micro Processor can also be denoted by (new symbol)

The word micro means small and process means processing(i.e.,Performing some computation).

Micro processor is able to perform larger and complex tasks in less amount of time....

Evolution of processors has made possibility  of high end performance achivement.

They even lead to great development of pcs,laptops,tablets....

They multiprocessing possible...With multiple processor built on one the other...
ex:Dual core,Quad core.....
Processors speed is measured in terms of Gigahertz.

processor working mechanism is baes on the cores of the processor.....
