Greetings: I have been lurking for some time and noticed remark by Janet regarding memory. I am an old man with limited computer knowledge and I found that the well known site "How Stuff Works" is quite educational. This URL will connect to the article on How Computer Memory Works: http://computer.howstuffworks.com/computer-memory.htm I have no interest in promoting the website and I hope this is not considered off subject. Thought it might be helpful. Thomas
