Project 802 defined network standards for the physical components of a network (the interface card and the cabling) that are accounted for in the physical and data-link layers of the OSI reference model.
The 802 specifications set standards for:
IEEE 802 Categories :
The LAN standards defined by the 802 committees are classified into 16 categories that can be identified by their 802 number as shown below:
802.1: Sets Internetworking standards related to network management.
802.2: Defines the general standard for the data-link layer. The IEEE divides this layer into two sublayers: the LLC and MAC layers (discussed in the previous lesson). The MAC layer varies with different network types and is defined by standard IEEE 802.3.
802.3: Defines the MAC layer for bus networks that use Carrier-Sense Multiple Access with Collision Detection (CSMA/CD). This is the Ethernet Standard.
802.4: Defines the MAC layer for bus networks that use a token-passing mechanism (Token Bus LAN).
802.5: Defines the MAC layer for token ring networks (Token Ring LAN).
802.6: Standard for Metropolitan Area Networks (MANs).
802.7: Used by the Broadband Technical Advisory Group.
802.8: Used by the Fiber-Optic Technical Advisory Group.
802.9: Defines integrated voice/data networks.
802.10: Defines network security.
802.11: Defines wireless network standards.
802.12: Defines Demand Priority Access LAN, 100BaseVG-AnyLAN.
802.14: Defines cable modem standards.
802.15: Defines wireless personal area networks (WPAN).
802.16: Defines broadband wireless standards.
