4 bits of data is called a "nibble." Why are nibbles so important? It's the least number of bits needed to represent the numbers 0 to 9. With 4 bits you have some extra spaces left over so to make efficient use of all the numbers available from 0 to 15, the characters A, B, C, D, E, F, is used in a base 16 number system.
