ANALOGY: Computer~~Mailroom
Imagine a mailroom with 256 mailboxes, numbered 0 through 255.
Each mailbox can contain only a single piece of paper with a number from 0 through 255 written on it.
One byte = 8 bits. A bit can be either “0” or “1”.
28 = 256 possible combinations of 8 bits. So every number can be represented.
