I, a computer, was a calculating machine in 1642 in France. Then I was built as an Analytical Machine in 1822, which was a technological revolution. I became a “universal machine” in 1936 to solve any mathematical problem. I was not very big at first, but then I became huge, the size of a large room before I was made smaller and smaller.
Getting new transistors in 1960s, I became cleverer and quicker. I was connected with other computers and turned out to part of a notebook in the early 1960. Then I began talking to human using BASIC in the early 1960s. In the 1970s, I was brought into people’s homes, and came the Internet.
