Some schools are really terrible at teaching technology. Some teach from the "how a computer works" perspective and some teach from the "how to use a computer" side. Not many teach both. Some just use them as glorified typewriters. Blech!
But.. I seldom will answer posts that look like homework. I'll give them references to sites or a few keywords and reference them to punch them into Google (after having tried it myself of course, so that I know the results they need will come up.

).
Interestingly, I work in high tech along the Rt. 128 belt here in Boston (a BIG high tech corridor) and the only things the schools seem to be interested in is having people come in and talk to the kids about what it's like to work in a high-tech type job. They have easy access to the people that design and build all this stuff but they just want them to come in and give kids pep talks.
