The First CPU

This article is about the evolution of the C P U or Central Processing Unit, the electronic gismo that operates the programs on a computer. Apparently C P U's where huge back in the day and had to have a pretty elaborate Air conditioning system, as well as a room pretty much to its self to keep it cool. It is very necessary to keep our computers cool even today it just takes less to do it. Instead of room for its self there are two small fans inside the tower or laptop to do the job. Check this site out. It has parts and some good advice on how to treat your computer.
