4. WHAT IS BINARY CODE?
Used in computers for encoding and translating data
Numbering system of base 2
Allows for only two states: 1 and 0
Can be used to represent situations that are true and false, on and off
Used with ASCII code to represent characters and strings

5. HOW DO I READ IT?
Each digit represents a power of 2 reading from right to left
Evaluate the powers and then multiply by the binary value (ultimately ignoring the zeros since that would result in zero......)
Add together and VOILA! your decimal value.
