Hello.
My problem is this: I need a way to learn about stuff like RAMs, Processers, Scanner, Firewalls, you know, computer stuff, that is online.
I want to learn more about computers and IT. The problem is, I don't know how to do it.
Can anyone help me?

It would be helpful if you tell some things about your background and the context in which you want to learn the things you ask.
