The only language any computer understands is one called machine code. It's written with two symbols: 0 and 1.

A memory chip houses millions of tiny switches, called transistors, which store all the computer's information, or data. WHY? Because inside every computer, there's at least one memory chip. Transistors can only exist in one of two states: - On, or 1, when electricity is flowing through it. - Off, or 0, when it isn't. A single 1 or 0 is known as a bit. A string of bits forms the binary code, which acts as a set of instructions that tells a computer what to do. In the binary code, each letter or command typed on a keyboard is converted into a line of eight bits. 'H' is 01001000, and 'i' is 01101001.
