A bit is enough room in which to store a zero, or a one but nothing else. A byte is eight bits grouped together. A nibble is four bits grouped together. A byte holds two nibbles, one being the first four bits, the other being the second four bits (respectively called upper nibble and lower nibble). Given that a bit can store a zero or a one, a nibble can store any combination of four bits from 0000 to 1111 and a byte can store any combination of eight bits from 0000 0000 to 1111 1111. These can be used to represent the numbers zero to 15 (in a nibble) or zero to 255 in a byte.

Binary digits are a basic unit of information storage and communication in digital computing and digital information theory. A bit is a binary digit. A binary digit is one that can only have one of two possible values, either 0 or 1. A value which is represented by 8 bits is referred to as a byte. For example, the value 10010111 is 8 bits long, and therefore a byte. The term "nibble" originates from the fact that the term "byte" is a pun on the English word "bite". A nibble is a small bite, which in this context is construed as "half a bite". A value represented by 4 bits is referred to as a "nibble. For example, the value 0110 is 4 bits long, and therefore "half a byte", or a "nibble".
