The computers are being extensively used to design and control  the machines  that can  imitate human  behavior  and  perform  the jobs  which  generally requires human  intervention. 

The Moore’s Law refers  the  observation  made  by Gordon Moore in 1965.  He was co-fonder  of  Intel corporation .

The Moore’s Law basically refers to his observation about rapidly increasing computing power of the today’s modern processor chips.

Moore's Law
Moore's Law in CS

The  invention of  transistor , which  is  a  tiny component made up of  silicon  was  a significant mile stone in the world digital electronics  . The silicon is  a semi conductor material . 

The  microprocessor  ( CPU )  is  the brain of the computer system  which actually provides the computing power to the computer system .

The CPU ( Central Processing Unit )  performs all the arithmetic calculations  and logical operations in a computer system .

The  computer’s processor  chip  is made up of  millions of these tiny component called  transistor . The transistor   is a fundamental  building block  for  all modern  processor chips .

Moore's Law

Moore's Law In Computer Science

As per Moore’s law , the number of transistors in a microprocessor  chip  will double about every two years. In other words , the Moore’s law states that the computing power of the processor chip  will double every two years  . 

The  Moore’s law further  predicts that this trend will continue into the foreseeable future.
