How does Steam work?

[DMB14]

How exactly does Steam work? I have it installed and I've been playing the HL2 demo. The HL2 demo isn't actually installed on my comp is it? Don't I just download it everytime I start Steam up?

I'm thinking about selling my computer and buying a new one. If I buy the HL2 Silver Edition ting through Steam can I play the games that it comes with on any computer as long as I sign in?

You can download steam on any pc, log in, and then download the games you want from the games you bought.

Ok, thanks. I'm going to go ahead and buy some games then.
