Charles Babbage
Alan Turing
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.
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.
