# of Bits is powers of 2 - not conversions Possibilities 2 4 8 16 32 BITS 1 3 5

How many bits would I need to represent the coordinates of the following grid If you have a 5X5 Grid 1 2 3 4 5

5X8 Grid STILL 6 bits because in 3 bits I can get 8 possible answers

What if 4 more show up – how many bits? If I have 4 people for dinner how many bits would it take to represent them? 2 bits – Powers2,4 What if 4 more show up – how many bits? Powers 2,4,8 - 3 bits

What is the minimum number of bits that you will need to encode a coordinate in that space? 15 X 8 4 bits for X and 3 for y 2,4,8,16 and 2,4,8 20 X 10 2,4,8,16,32 and 2,4,8,16 5 + 4 =9
