He called them the Big-Endians and the Little-Endians. In the 1726 novel Gulliver's Travels, he portrays the conflict between sects of Lilliputians divided into those breaking the shell of a boiled egg from the big end or from the little end. The adjective endian has its origin in the writings of 18th century Anglo-Irish writer Jonathan Swift. Danny Cohen introduced the terms big-endian and little-endian into computer science for data ordering in an Internet Experiment Note published in 1980. Bit-endianness is seldom used in other contexts. Įndianness may also be used to describe the order in which the bits are transmitted over a communication channel, e.g., big-endian in a communications channel transmits the most significant bits first. Other orderings are generically called middle-endian or mixed-endian. Bi-endianness is a feature supported by numerous computer architectures that feature switchable endianness in data fetches and stores or for instruction fetches. A big-endian system stores the most significant byte of a word at the smallest memory address and the least significant byte at the largest.Ī little-endian system, in contrast, stores the least-significant byte at the smallest address. Endianness is primarily expressed as big-endian ( BE) or little-endian ( LE). In computing, endianness is the order or sequence of bytes of a word of digital data in computer memory. The adjective endian comes from the 1726 novel Gulliver's Travels by Jonathan Swift where characters known as Lilliputians are divided into those breaking the shell of a boiled egg from the big end ( Big-Endians) or from the little end ( Little-Endians)
