how do i became computar literate?

On a serious note, how would I go about doing this? I'm not saying I'm a complete fucktard with computers, but I want to learn more than I already do. Lately, I've been wanting to get into programming again (before it didn't work out, because I didn't know anything about hardware), but this time I want to actually know what I'm doing. I know all the basics (TCP/IP, hardware, etc). What should I look at to learn more stuff?

help appreciated.

I just want to be able to define everything that I may see in any kind of discussion / programming topic. Like, for example, "registers" and "addresses" (like you mentioned). I basically want to get more in-depth with that kind of stuff.
