How many bits are there in a nibble?

A nibble is a term used in digital electronics and computer science to refer to a group of four bits. This terminology arises from the fact that a nibble is half of a byte, which consists of eight bits. In binary notation, each bit can represent a value of either 0 or 1, and with four bits, you can represent numbers from 0 to 15 (in decimal), or 0000 to 1111 (in binary).

Understanding the size of a nibble is essential because it forms a fundamental building block in data representation and processing. Knowing that a nibble holds four bits can help when dealing with hexadecimal number systems, which are often used in computing to compactly represent binary information, as each nibble directly corresponds to a single hexadecimal digit (0 through F).
