LAN, wait a second!

So I set up a LAN between my desktop PC and my laptop via LAN cable but eventually I noticed that it worked even when the cable wasn't connected, you know, because both of them have wireless internet antennas. It took some time to realize as they looked to be about the same speeds, but actually aren't (54Mbps and 100Mbps). So maybe I don't even need the cable after all, it's borrowed anyway.

So I was wondering, when I send stuff between computers I'm not using my internet downloads/uploads, right? Right?

Someone who's too dense to figure out fucking Google and instead decides to waste our time by asking retarded questions is a fucking moron.
Don't expect us to help if you can't be bothered to do a tiny bit of research.
