If you want to understand more about how computers work you'll want to take a look at these links from John Carter. He writes, "Albert Wenger has a blog called Continuations. Although Albert’s daytime job is working at a Venture Capital firm, he seems to be doing quite well at explaining how computers work in his Tech Tuesday column."Scroll down to "Computer’s Building Blocks" and to "Of Bits and Bytes." John closes with "Anyone new to computers will undoubtedly come away with a better understanding of the innards of a computer."
Beware! This is VERY techie!
