1) Computers use binary because the circuit boards they are made from have gates, 0 meaning off and 1 meaning on. So basically when its off, no electricity passes through that part, and when its on, electricity passes through. Theres no inbetween.

2) No idea

3) A byte is 8 bits. For instance, a computer keyboard, everytime you hit a key, sends 8 digits of 0's 1's, to the computer for processing.
A Kilobyte, is 1024 of these bytes, of 8 bits.

4) No idea
