18. Alan Turing Charles Babbage

19. In 1642, a calculating machine was used in France. Then in 1822, the Analytical Machine was made by Charles Babbage. It could follow instructions from cards with holes. In 1963, Alan Turing, the real father of computers, wrote a book about how the computers could be made to work as a “universal machine” to solve any difficult mathematical problem. Later, people discovered the computer had “artificial intelligence”. In the 1960s, the computer had his new transistors.

20. Its size was totally changed at that time. And in the early1960s, the first family of computers were connected to each other. In 1970s computers have brought into people’s homes. Now computers have been used by billions of people to deal with information and communicate with each other around the world by the Internet.
