History Of Computer Science
The Computers are today integral part of the human world and human world today critically depends upon the computing power of today’s modern computers .
The Computer Science has also evolved over period of last few decades both in the hardware and software domain.
However , The history of computer science began , long before our today’s modern discipline of computer science.
In the past seventy years , the computers have migrated from room-size mega boxes to the desktops computers.
And now the computers are in our pockets with far more computing power and mobility .
But the modern computing-machine era began with Alan Turing’s conception of the Turing Machine, and the three Bell Labs scientists invention of the transistor .
The transistor is a tiny electronic component made-up of silicon . It is extensively used in many electronic devices.
The Transistor is used as a micro switch and a fundamental building block for all digital electronic devices including computers .
The invention of transistor has made modern-style computing possible. This invention rewarded them with the 1956 Nobel Prize in Physics.
Applications Of Computer Science
The advancement in science and technology has completely transformed the human world . The human world is now moving towards the machine age with the advent of powerful computers armed with artificial intelligence .
The computers can now design and control the machines that can imitate human behavior and perform the jobs which generally requires human intervention .
Applications Of Computer
- Aviation.
- Engineering CAD , CAM.
- Manufacturing.
- Healthcare.
- Banking And Finance.
- Education.
- Military And Defence.
- Scientific Research.
CS And Moore's Law
The computer hardware and software design technology is also changing at a rapid pace .
The early room size computers are now reduced to pocket size with far more computing power .
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 .
Moore's Law
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.
