Computers

September 07, 1998

People use computers to perform an amazing array of tasks: from conducting scientific experiments and creating movie special effects to communicating with people around the world. We're used to seeing computers on our desks at home, school or work but the first computer, the ENIAC in 1945, took up 1,000 square feet of floor space and used 160 kilowatts of electrical power. To find out more about computers, use the direct links on The Times Launchpoint Web site:
