Although numbers are processed inside a computer as binary, that doesn’t mean that we need to always represent these numbers as binary to humans.
As we have previously mentioned our counting system is based on 10's and computer is based upon 0's and 1's.
If you think B7 is easier and more convenient to remember and use, you now understand why some binary is expressed in hexadecimal format. B7 is actually the same value as 1011 0111; however, it is represented as hexadecimal instead of binary.
Hexadecimal is a base 16 number system: it makes use of 16 numbers. So if we had a creature with 16 fingers, this is how they would count using hexadecimal:
Nibbles are 4 bits or half a byte
