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.
4. Which of the following statements is TRUE?
A. Charles Babbage built an Analytical Machine in 1642.
B. A “universal machine” was built to solve any difficult mathematical problem in 1936.
