a“strange machine”to solve any mathematical problem. Earlier I was not very big, but then I became huge！However, people thought I was simple­minded until they discovered I had artificial intelligence.“Artificial！”I didn't know what they were talking about. Anyway, let's go back to my history. Then I was the size of a large room! As the years have gone by, I have been made smaller and smaller.

No one could recognize me after I got my new transistors (晶体管) in the 1960s.There were times when my size was totally changed.I became small and thin but I got cleverer and cleverer, quicker and quicker.And my memory became so large that I couldn't believe it！But I was always so lonely standing there by myself.In the early 1960s they gave me a family connected by a network.I could share information with others and we could talk to each other.At about the same time we learned to talk to humans using BASIC. I was brought into people's homes in the 1970s.Since then, my family and I have been used by billions of people to deal with information and communicate with each other around the world by the Internet.I love being used to connect people who aren't close enough to speak to each other.I have truly been built to serve the human race since my birth.
