BITS, NIBBLES, AND BYTES
We briefly covered the length of the number. The length of a binary number is the amount of 1’s and 0’s it has.
Common binary number lengths Binary values are often grouped into a common length of 1’s and 0’s, this number of digits is called the length of a number. Common bit-lengths of binary numbers include bits, nibbles, and bytes (hungry yet?). Each 1 or 0 in a binary number is called a bit. From there, a group of 4 bits is called a nibble, and 8-bits makes a byte. Bytes are a pretty common buzzword when working in binary. Processors are all built to work with a set length of bits, which is usually this length is a multiple of a byte: 8, 16, 32, 64, etc. To sum it up:
Length Name Example 1 Bit 0 4 Nibble 1011 8 Byte 10110101

Word is another length buzzword that gets thrown out from time-to-time. Word is much less yummy sounding and much more ambiguous. The length of a word is usually dependent on the architecture of a processor. It could be 16-bits, 32, 64, or even more.
