Byte

A byte is a basic unit of digital information in computing whereby information is stored and transmitted in the form of bits, usually eight of them, though some systems use seven. It is mainly employed to describe the number of memory units needed for the encoding of a single character of text within a given computer system. Due to the fact that a byte is the smallest unit of memory that can be addressed in a given architecture a byte is a crucial component of data storage and manipulation. For instance, to store the letter ‘P’, one byte of memory is needed while to store the word ‘Path’, four bytes are needed and each byte represents one of the characters in the text.

The byte was defined in 1956 by Werner Buchholz and has ever since been an essential part of computer memory design. Not all the bytes are employed to store text characters as there are other data types, for instance, numbers, symbols, and control codes. Memory organization and data control is a crucial concept in contemporary computing and depends on the byte since it defines the amount of memory required to store data and the ways through which the data can be accessed and manipulated by the system. It is for this reason that the byte is an important component in the construction of both software and hardware, where the management of memory is a very important aspect of the system.
