Nibble

Nibble is a way of counting in binary. Binary is like a secret code made up of only two numbers - 1 and 0. A nibble is one of these binary numbers. It is made up of four binary numbers - for example, 1010. You can use nibbles to count up to fifteen (because a single nibble is only enough to count up to fifteen). For example, the nibble 0000 means zero, 0001 means one, 0010 means two and so on. So nibbles are a way of counting in binary and a special way of counting from zero to fifteen.
