1.2 LAN Standards and Terminology

The LANs commonly referred to as Ethernet LANs are defined by two standards, the Ethernet version 2.0 standard (DIX) developed by DEC, Intel, and Xerox, and the ISO 8802-3 standard (IEEE 802.3), which is an international version of the DIX standard. Since the ISO 8802-3 includes the DIX standard, network equipment built to those standards will be basically compatible.

Since the Ethernet Port physical layer has a structure that conforms to the ISO 8802-3 standard, users must be sure to use network equipment that conforms to the ISO 8802-3 standard.

The networking terminology used in this document is the terminology used in the ISO 8802-3 standard. Table 1.3 presents the correspondence between the DIX standard terminology (common terms) and the ISO 8802-3 standard terminology.
