Octet

Overview#

Octet is a unit data in computing and Telecommunications that consists of eight bits.

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.

A variable-length sequence of Octet, as in Abstract Syntax Notation One (ASN.1), is referred to as an OctetString

Octet can be represented using number systems of varying bases such as the hexadecimal, decimal, or octal number systems. The binary value of all eight bits set (or activated) is [111111112], equal to the hexadecimal value [FF16], the decimal value [25510], and the octal value [3778].

One Octet can be used to represent decimal values ranging from 0 to 255.
