Today, we use computers in factories and offices, schools, hospitals, and in our houses. Our computers are now small enough for us to carry, and some of them are relatively cheap. This is why more and more people can use them at work or at home.

In 1940, some English scientists made the first electronic computer in Europe. This computer was too big to carry or move, and also used a lot of electricity. Scientists had to find new and better ways to make the electronic parts of computers. They had to make computers small enough to carry and move easily.

Since 1940, computers have become smaller and smaller. Some small pocket calculators today can do more difficult calculations than the first big electronic computer.
