Computers concern you

     When Charles Babbage, a professor of mathematics at Cambridge University, invented the first calculating machine in 1812 he could hardly have imagined the situation we find ourselves in today. Nearly everything we do in the modern world is helped, or even controlled, by computers, the complicated descendants of his simple machine. Computers are being used more and more extensively in the world today, for the simple reason that they are far more efficient than human beings. They have much better memories and can store huge amounts of information, and they can do calculations in a fraction of the time taken by a human mathematician.

     No man live can do 500,000 sums in one second, but an advanced computer can. In fact, computers can do many of the things we do, but faster and better. They can pay wages, reserve seats on planes, control machines in factories, work out tomorrow’s weather, and even play chess, write poetry, or compose music. Let’s look now at some of the ways in which computers concern people in their daily lives and work.

    Chief Inspector Harston talks about ways in which computers can help the

police fight crime. "Members of the public often think of detective work as fast and exciting when most of it is slow and boring. For example, a detective on a stolen car case may have to check through long list of information, and in the time it takes him to do this the thief may well escape. With the new National Police Computer we are now able to find out details of car ownership and driving license in a fraction of the time it takes by traditional methods. We are also developing systems of storing fingerprint information in computers and even information about people’s appearance. It’s possible to work out codes for visual details and to link a computer with a videotape recorder (VTR). Then, instead of looking through books of photographs we’ll be able to ask the computer to sort out the right ones, and see photographs of suspects flashed across a VTR screen. In police work speed is often essential, so computers are ideal for helping us catch criminals. The only problem is that we now have a new kind of criminal – the very clever man who knows how to make huge sums of money by cheating a computer, and he is very difficult indeed to catch”.
