Math in Computer Science?!

We finally finished our words definitions today, and learned about the binary codes. The new and interesting thing I learned today is how to count, and not just the regular way (base 10), we learned base 2!! It may not sound like much, but it's actually very cool. Did you know, if you do addition with base 2, 1+1=10? And the only 2 numbers that can be used in it are 0 and 1. For homework, I updated/validated and put the basic computer glossary on the web. I've had some troubles validating the class glossary though because one of the errors said that I needed to add a <dl> when I already had one. I also found pictures for the newly defined words we got in class, but I still couldn't find the right pictures for megabyte, gigabyte, kilobyte, bit and byte.
