![]() In 2000, Bob Bemer claimed to have earlier proposed the usage of the term octet for "8-bit bytes" when he headed software operations for Cie. The earliest example is RFC 635 from 1974. ![]() It is frequently used in the Request for Comments (RFC) publications of the Internet Engineering Task Force to describe storage sizes of network protocol parameters. The term octet (symbol: o ) is often used when the use of byte might be ambiguous. One octet can be used to represent decimal values ranging from 0 to 255. The binary value of all eight bits set (or activated) is 11111111 2, equal to the hexadecimal value FF 16, the decimal value 255 10, and the octal value 377 8. Octets can be represented using number systems of varying bases such as the hexadecimal, decimal, or octal number systems. While byte and octet are often used synonymously, those working with certain legacy systems are careful to avoid ambiguity. This meaning of byte is codified in such standards as ISO/IEC 80000-13. Due to the influence of several major computer architectures and product lines, the byte became overwhelmingly associated with eight bits. ![]() However, the unit byte has historically been platform-dependent and has represented various storage sizes in the history of computing. The international standard IEC 60027-2, chapter 3.8.2, states that a byte is an octet of bits. The term octad(e) for eight bits is no longer common. The term is often used when the term byte might be ambiguous, as the byte has historically been used for storage units of a variety of sizes. The octet is a unit of digital information in computing and telecommunications that consists of eight bits.
