Binary, Hex and ASCII.

Binary is made up of 1's and 0's.
The most common use of binary is 8-bit binary.
Which goes right to left in the order 1, 2, 4, 8, 16, 32, 64, 128
167 in 8-bit Binary would be

128 | 64 | 32 | 16 | 8 | 4 | 2 | 1
1     | 0   | 1   | 0   | 0 | 1 | 1 | 1

Hex goes in sets of 16
so the Hex number 32 the 3 stands for 3 sets of 16 (48) and 2 extra so that would be 50
A=10 B=11 C=12 D=13 E=14 F=15
