How many bits are in one nibble ?

Computer data is measured in units built from the bit, the smallest unit of digital information, which can be either 0 or 1. Larger units are formed by grouping bits together: a byte is made of \(8\) bits, and a nibble is defined as exactly half of a byte.

Since a byte contains \(8\) bits, half of that amount is\[\frac{8}{2} = 4\]bits. A nibble is therefore made up of \(4\) bits, which is enough to represent a single hexadecimal digit, one reason the nibble is a useful unit in computing.

Keep the size chain in mind: \(4\) bits make a nibble, \(8\) bits (two nibbles) make a byte, and multiples of bytes build up to kilobytes, megabytes, and beyond.
