Now, I'd like to tell you about the development of computers. Computers
began a calculating machine in France in 1642, it could
(simple) difficult sums. In 1936, Alan Turing wrote a book about how a computer
could be made to work as a "universal Machine" (solve) any
difficult mathematical problem. By the 1940s, computers had grown as large as a
room. As time went by, they were made (small). Since the 1970s
computers (use) in offices and homes, first as personal computers and
then as laptops.
As computers' memory improved, computers became much smaller and more
(intelligence). First the memory was stored in tubes, then on transistors and
later on very small chips. Over time computer's memory (develop) so
much that computers remember everything they have been told. In the early 1960s
computers could be connected to each other by the network (call) the
World Wide Web.
Many new (apply) have been found for computers since the1970s.
They have been used in communication, finance, trade, robots, mobile phones, space
rockets and so the goal of computers is to provide humans a life of
high quality.
