The summary about the text
The computer began only as a calculating machine in 1642, then in 1822, it was built as an Analytical Machine by Charles Babbage . At the year of 1936, Alan Turing wrote a book to describe how computers could be made to work, and build a “universal machine “ to solve mathematical problem. With the development of information technology, in the 1960s, computers had new transistors and became smaller and smaller, then were connected to each other by the internet. As the years had gone by, computers were brought into peoples’ homes. Now computers have become the most important tools to connect people all over the world together.
Read the text carefully, find out the difficult points.
