Difference between Bit, Nibble, and Byte

A bit is either 0 or 1, a group of 4 bits is a Nibble, and 8 bits make a Byte.

Comparison between Bit, Nibble, and Byte

Bit

The Bit (short for Binary Digit) is the smallest unit of digital data. A single Bit can have a maximum of two values, 0 or 1.

The below chart compares some popular Numeral Systems and Possible values for a single digit.

Nibble

A Nibble is a group of 4 bits. If we arrange the bits in a Nibble into unique combinations, it can hold decimal values from 0 to 15. That means it can represent 16 values.

Byte

A byte contains 8 bits. We can arrange the Bits in a Byte into 256 unique combinations to represent decimal values from 0 to 255.
