|Description:||Byte, 8-bit value|
An Octet is an ordered collection of 8 bits, which equals an 8-bit Byte, regardless of the numerical system representing it.
This term is used in many standards, especially for Network-Protocols, to represent an 8-bit value.
In France, French Canada and Romania, octet is used in common language instead of (an 8-bit) Byte.
In very early days of the chmod command each octal number of a numerical permission was erraneously called an octet.
This happened due to the 8 possible values a 3-bit octal number could represent, and was stopped long ago to avoid confusion.
An IPv4 address is defined to consist of 4 octets, which are commonly written dotted decimal (0-255 each octet).
