Explanation:
Detailed explanation-1: -A group of four bits is also called a nibble and has 24 = 16 possible values.
Detailed explanation-2: -In computing, a nibble (occasionally nybble, nyble, or nybl to match the spelling of byte) is a four-bit aggregation, or half an octet. It is also known as half-byte or tetrade.
Detailed explanation-3: -The term is a play on the word ‘bite’ and alludes to being a fraction of a byte. More precisely, a nibble corresponds to half of a byte and thus four bits. The nibble unit was developed in collaboration with the BCD code (Binary Coded Decimal), in which four bits each represent a digit between 0 and 9.
