What are Nybbles?

Nybbles are a unit of measurement used in computer science and electronics to represent small groups of binary digits (bits). A nybble is a group of four bits, and it is often used to represent a single character or a small number.

For example, if we have a string of characters that we want to represent using only four bits, we might use a nybble to represent each character. So, the letter "A" might be represented by the binary sequence "0100", which would be stored as a nybble with the value "0100". Similarly, the letter "B" might be represented by the binary sequence "1000", which would also be stored as a nybble with the value "1000".

Nybbles are often used in computer programming and electronics because they provide a convenient way to represent small groups of binary digits. They can be used to store information about characters, numbers, or other small pieces of data that don't require a full byte (eight bits) to represent.
