What is the definition of a 'nibble' in data representation?

• A. 8 bits
• B. 4 bits
• C. 2 bits
• D. 16 bits

Answer: (B)

A 'nibble' is defined as 4 bits in data representation. This term comes from the combination of "nibble," which is derived from "byte," as a byte traditionally consists of 8 bits. Since a nibble is exactly half of a byte, it allows for the representation of 16 different values, ranging from 0000 to 1111 in binary notation. This representation is often used in computing and digital electronics, particularly in hexadecimal number systems, where one hexadecimal digit corresponds to one nibble. In contrast, terms like a byte (8 bits), half-byte, or other specific bit sizes do not represent the same concept as a nibble, which clearly identifies this 4-bit grouping.
