What good resources are there for a high school student to start learning electronics?

I have a couple years of experience with computers - I can program, and I know computers really well. But I don't understand them.

This leads to a broader scope - I don't understand electronics in general. I have read some internet articles, like howstuffworks.com, that kind of thing. I understand the basics, but about 90% of it is beyond me.

Where do I learn? What books can I read? What websites can I go to? I'm especially interested in knowing what books I can read to understand more about electronics.
