The byte (/ËbaÉªt/) is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures.The size of the byte has historically been hardware dependent and no definitive standards existed that mandated the size.NET programming languages, such as C#, define both an unsigned byte and a signed sbyte, holding values from 0 to 255, and -128 to 127, respectively. In data transmission systems, the byte is defined as a contiguous sequence of bits in a serial data stream, representing is the smallest distinguished unit of data.
Why it matters-If you use a package like FTP to download a web-based Text (i.e. ASCII) file (where Unix is the assumed operating system) to an MS-DOS based system, the FTP process will automatically scan the file and replace each line feed character with a carriage return-line feed pair. byte is the collection of bits used by a particular computer for the most common character encoding scheme used by that computer. The most common byte size is 8 bits, but 6, 7, 9, and 12-bit bytes are used by some (different) computer systems.
