The IEEE 802 Standard comprises a family of networking standards that cover the physical layer specifications of technologies from Ethernet to wireless. IEEE 802 is subdivided into 22 parts that cover the physical and data-link aspects of networking. The better known specifications include 802.3 Ethernet, 802.11 Wi-Fi, 802.15 Bluetooth/ZigBee, and 802.16.
All the 802.11 specifications use the Ethernet protocol and Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) for path sharing. The original modulation used in 802.11 was phase-shift keying (PSK). However, other schemes, such as complementary code keying (CCK), are used in some of the newer specifications. The newer modulation methods provide higher data speed and reduced vulnerability to interference.

IEEE 802.1
Bridging (networking) and Network Management
Network bridging describes the action taken by network equipment to allow two or more communication networks, or two or more network segments, to create an aggregate network. A network bridge is a network device that connects more than one network segment. In the OSI model bridging acts in the first two layers, below the network layer.
IEEE 802.2
LLC
In the seven-layer OSI model of computer networking, the logical link control (LLC) data communication protocol layer is the upper sublayer of thedata link layer, which is itself layer 2. The LLC sublayer provides multiplexing mechanisms that make it possible for several network protocols (IP, IPX,Decnet and Appletalk) to coexist within a multipoint network and to be transported over the same network medium. It can also provide flow control andautomatic repeat request (ARQ) error management mechanisms.
IEEE 802.3
Ethernet
Ethernet is a family of computer networking technologies for local area networks (LANs). The Ethernet standards comprise several wiring and signaling variants of the OSI physical layer in use with Ethernet.
