CS And Moore's Law
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.
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 .
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.
