The Computer:-The first operational electro-mechanical computer was used to crack secret codes. Innovation has miniaturized computers while increasing their power exponentially: the transistor(1947),the integrated circuit(1959)and the microprocessor(1970),increased the speed to process data,while the hard disk(1956),modem(1980)and mouse(1983)boosted their power to make data accessible.They now fit in our pocket and the palm of our hand. The Internet:-It runs on computer,It is a secret project,the internet served as a communication network that would remain intact,even if several of its strands were broken.While most of the world was celebrating Woodstock, two computers in southern California exchanged information. The Net has emerged into mainstream culture after Tim Berners-Lee thought up a structure of links and addresses for sending data unhampered by central authority and proprietary software-bringing the internet to life and effectiveky making the globe a village by fostering the sharing of information. And this is also a method of earning money and products of our day to day life.
