Self-study book by Alexander Levin, if you really are a humanist and love to read :) Once it helped a lot to master the computer that was brought and installed, and I only knew how to turn it on. Levin does not tensely touch on many topics and popularly explains the meanings of many "terrible words".
Yes, I think any internet forums will be enough. These two words definitely don't have any problems. Go to the site, something does not work for you, you ask why, they tell you to contact the system administrator, and he says to try to disable the firewall. Well, isn't it all simple? = D I met both of these words in grade 5, when I didn't even really think about what to become, and used the Internet only for communication, video games and the development of a little brain, but you yourself understand that then I didn't really want to learn something hard. Therefore, I learned a lot of nuances the hard way.> Reading experience.
