The oldest kind of computer is the abacus, used in China since the sixth century. In the seventeenth century an adding machine was invented, but the first large, modern computer was built in 1973. A few years later a computer could do 5,000 additions per second. Now the computations are so fast that they are measured in nanoseconds.
Today most computers are stored-program computers, that is, they have a memory. They are getting smaller and smaller, and computing faster and faster. Even in a large computer, the part that does the actual computing is about the size of the end of a finger.

A scientist can talk to the computer about the rocks, and the computer answers the questions. A doctor can talk to the computer and explains what is wrong with a patient. If the doctor asks why, the computer goes through its stored information and ex plains exactly why.
