You do know who the first calculating machine has been invented by, I hope. No, you don’t?

It was invented by Charles Babbage, a professor of mathematics at Cambridge University, in 1812. that device could do complicated calculations faster than people were able to.

A computer was invented in the 20th century. The first computers were very big as there were thousands of tubes in them. That is why they were not widely used for a long time. Only when scientists invented transistors and then integrated circuits and later microcircuit chips, the computers became popular and many people began to use them widely as they were small and could be placed on a writing desk in a flat. In addition, they could do calculations much faster. Now a computer can do one million sums a second and even much quicker. No man can do that.

At present computers are used widely because they do everything in a more efficient way than people. They can calculate the orbits of spaceships, control machines in factories and plants, reserve seats on planes, pay wages, play chess or cards, compose music, translate from one language into another.

Different experts can’t do without them: researchers, doctors, teachers, students, schoolchildren, librarians, composers, designers, engineers, etc.

How much information computers can store in their memories! They are ready to help people at any moment. In fact, they can do many of the things we do, but faster and better.

Today computers control nearly everything we do in the world. They serve everyone in his everyday life. Do you agree?
