Meaning – The term N-bit byte, refers to a string that consists of n bits.
The bitis the most basic unit of information in computing and digital communications. The name is a contraction of binary digit. The bit represents a logical state with one of two possible values. These values are most commonly represented as either “1” or”0″, but other representations such as true/false, yes/no, +/?, or on/off are common.
The correspondence between these values and the physical states of the underlying storage or device is a matter of convention, and different assignments may be used even within the same device or program. It may be physically implemented with a two-state device.
Example of usage – “A contiguous group of binary digits is commonly called a bit string, a bit vector, or a single-dimensional (or multi-dimensional) bit array. A group of eight binary digits is called one byte, but historically the size of the byte is not strictly defined.”
