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.

read. that's pretty much it.
