>> Bits and bytes
> Any information - text, audio, video, numbers - can be easily converted into, and out of binary code, which is why it is used so often in computing.
> Each 1 or 0 is referred to as a 'bit' (a 'binary digit'), and a set of 8 bits is called a byte.
> So, a computer with 320 GB - 320 gigabytes - of memory can store 320,000,000,000 bytes, and each byte means something to the computer: a letter, or a number.
