How many bits are contained in a nibble?

A nibble is a term used in computer science to refer to a unit of digital information that consists of 4 bits. This is half a byte, as a byte is typically composed of 8 bits. In binary, each bit can hold a value of either 0 or 1, so with 4 bits in a nibble, you can represent 16 different values (from 0000 to 1111 in binary). This representation is commonly used in contexts such as hexadecimal notation, where each nibble corresponds to a single hexadecimal digit. Understanding the relationship of bits, nibbles, and bytes is fundamental in computing, especially in memory and data representation.
