• A number is represented as the base 2 number held in some pre-ordained fixed number of bits
• Almost all other data is represented as various sets of numbers.
• A byte is 8 bits sequenced together - what is the maximum number?
• Integers (in Java and most other languages nowadays) are 32 bits long - what is the maximum number?
