Research into Generations of Computers Over the last 60 years computers have developed from a thirty ton monstrous machine with 19,000 vacuum tubes, 1,500 relays, hundreds and thousands of resistors, capacitors and conductors that consumed almost 200 kilowatts of electrical power into a small met...

The History of Computers Man has always looked for easier ways to solve mathematical problems. One of the earliest machines known and still used at times, is the abacus. By moving the beads on their rods you could compute numbers. Beginning in the late 1600's people started inventing machi...

Computers are such an integral part of our society that it is sometimes difficult to Imagine life without them. However, computers as we know them are relatively new devices. In fact, the first electronic computers were built just over fifty years ago. Since that time, the technology has advanced...

Early Computational Devices Somewhere around 3000BC the first mechanical counting device created was the abacus. The abacus is still used today and, amazingly to me, with great speed and accuracy. In 1642 another mechanical device was created called the Pascaline (after Blaise Pascal, a fa...
