1. I owned that keyboard. It connects via a 2.4Ghz Logitech Unifying receiver. This is a teeny USB dongle that the keyboard talks to. Teeny as in it sticks out 1/4". You wouldn't see it if you weren't looking for it
2. Batteries, distance, wireless in general...all come into play for a wireless keyboard.
3. You're 12, dude. The minimum age here is 13.
Closing this.
