An example of a byte is combination of bits used in computer coding to represent a letter in an alphabet.
- a string of binary digits (bits), usually eight, operated on as a basic unit by a digital computer
- the basic unit of storage capacity in a computer system
Origin of bytearbitrary formation
- A unit of data equal to eight bits. Computer memory is often expressed in megabytes or gigabytes.
- A set of bits constituting the smallest unit of addressable memory in a given computer, typically eight bits.
Origin of byteAlteration and blend of bit3 and bite.
byte - Computer Definition
(BinarY TablE) The common unit of computer storage from desktop computer to mainframe. It is made up of eight binary digits (bits). A ninth bit may be used in the memory circuits as a parity bit for error checking. A byte holds one alphabetic character such as the letter A, a dollar sign or decimal point. For numeric data, one byte holds one decimal digit (0-9), two "packed decimal" digits (00-99) or a binary number from 0 to 255. From Bite to Byte IBM coined the term in the mid-1950s to mean the smallest addressable group of bits in a computer, which was originally not eight. The first spelling was "bite," but the y was added to avoid accidental misspelling between "bite" and "bit."
Byte SpecificationsDrives and memory (RAM) are rated in bytes. For example, a 500-gigabyte (500GB) hard drive stores 500 billion characters of program instructions and data permanently, while four-gigabytes (4GBs) of RAM hold four billion temporarily. In early personal computers, hard drives were 5MB, and memory was 64K. See memory and file size.
A character in a computer coding scheme.A byte is a unique set of adjacent bits with a unique meaning in a computer coding scheme. A byte generally comprises eight (8) bits that represent a letter in an alphabet (e.g., a, A, z, or Z), a diacritical mark (e.g., ~ or `), a single digit number (e.g., 0, 1, 2, or 3), a punctuation mark (e.g., ,, ., or !), or a control character (e.g., paragraph break, page break, or carriage return).The size of a byte is specific to the coding scheme involved. For example, ACSII employs a coding scheme of seven (7) bits, so a byte is actually seven information bits, although the addition of a parity bit Bridge < 500 m < 2.5 km Terminator for error control results in a byte of eight (8) bits for storage and transmission purposes. An EBCDIC byte is truly eight (8) information bits. Unicode variously employs eight (8) and 16 bits. Computers create, store, manage, and output information in bytes.The origin of the term is uncertain, although it is certain that Dr. Werner Buchholz originated the term byte in 1956 when working for IBM on the STRETCH computer. Some suggest that byte is an alteration and contraction of bit, referring to the basic unit of information, and bite, referring to a morsel or chunk of data consumable by the early computer eight-bit processors. Others suggest byte is an acronym formed from binary digit eight. Still others suggest that byte is short for binary term. Computing and storage systems measure memory and storage capacities in bytes. For example, a kB (kiloByte) is actually 1,024 (2 10 ) bytes, since the measurement is based on a base 2, or binary, number system.The term kB comes from the fact that 1,024 is nominally, or approximately, 1,000. So, 64 kB of memory is actually 1,024
