All of us think about a computer. That’s why we ask: “what is a computer” A computer is one of the modern technologies using everywhere. It is a complex instrument made up of electronic devices, miles of electronic wire. Its complex electronic brains produce information. This information is stored on magnetic? An operator can feed figures and symbols into the machine. When an operator wants to receive answers, he asks the machine in a special language to process the information taken from storage. The electronic machine can give any answer or a combination of possible answers. At a panel desk connected to the instrument, the machine can flash its answers on a screen, can print them on paper, and store them away on magnet tapes or cards.
Of cause, more than 100.000 pieces of information can be stored in one machine. The computer can do a lot of operations.
For example, the computer can multiply large numbers. How long does it take the computer to multiply large numbers? In one third of a second a computer can multiply two 127-digit numbers. In whole second, it can add 4.000 five-digit numbers. In two seconds it can computer 320 long-division problems. The same machine does the work of thousands of trained mathematicians in any given time period and without the mistakes. But … human beings do thinking, feed information to the machines. The computer only helps us to find answers and produce facts faster and more accurately.
Machines work for us, but they do not think for us.
