A nibble is __________.

A nibble is defined as 4 bits, which is half of a byte. In digital computing, a byte consists of 8 bits, so when you divide a byte in half, you get a nibble, making this term particularly useful when representing binary-coded numbers or characters that fall within the range of 0 to 15, as each nibble can represent one hexadecimal digit. This understanding is foundational in areas like computer architecture and programming, where data representation is essential. Other options listed describe larger groupings of bits that do not align with the definition of a nibble.
