Binary Numbers
- Computers use binary numbers, which are made up of 0s and 1s.
- Each 0 or 1 is called a bit.
- Each bit represents a power of 2 from 2^0 to 2^7.
- In the activity that follows, 2^0 is on the right.
- A group of 8 bits is called a byte.
- A byte can represent a number from 0 to 255.
- The number 255 is the largest number that can be represented by a byte.
- The number 0 is the smallest number that can be represented by a byte.
