The transistor

A transistor is a small device that can count to one! Every computer, computer game, mobile telephone and camera contains lots of lots of transistors. Even the cheapest mobile telephone contains more than 20 million transistors.'

The great advantage of the transistor is that it is tiny and fast. Although it can only count up to one, they manage to listen to everything we say on a mobile telephone, they immediately reproduce everything in the form of a sum and send it into the air to another telephone.

The transistor was invented in New York in 1946 the day before Christmas Eve. At the time it was as big as a golf ball and was made of the crystal Germanium. Nowadays transistors are manufactured in China, Korea and India made of the same element found in sand, namely silicon.
