802.11 is a group of wireless specifications developed by the IEEE for wireless local area network (WLAN) communications. It details a wireless interface between devices to manage packet traffic to avoid collisions. Some common specifications include the following: 802.11a, 802.11b, 802.11g, 802.11n, etc.

802.12 is an IEEE standard which defines the 100 VG-Any LAN standard. 808.12 specifies the physical layer and the MAC sublayer of the data link layer. IEEE 802.12 uses the demand priority media-access scheme at 100 Mbps over a variety of physical media.

IEEE 802.15, a group of standards of wireless communicatoins defined by IEEE, is for wireless personal area networks (WPANs). IEEE 802.15 has characters such as short-range, low power, low cost, small networks and communication of devices within a Personal Operating Space. The current technologies included in the IEEE 802.15 family are: 802.15.1 (Bluetooth), 802.15.2 (UWB) and 802.15.4 (ZigBee).

The IEEE 802.16 refers to a group of standards that defines wireless communications between a subscriber site and a core network such as the public telephone network (PSTN) and the Internet. It is called Wireless MAN technology, which is also branded as WiMAX. This wireless broadband access standard provides the missing link for the "last mile" connection in metropolitan area networks where DSL, Cable and other broadband access methods are not available or too expensive.

IEEE 802.2 LAN protocol specifies an implementation of the LLC sublayer of the data link layer. IEEE 802.2 LLC is used in IEEE802.3 (Ethernet) and IEEE802.5 (Token Ring) LANs to perform these functions:
a. Managing the data-link communication
b. Link Addressing
c. Defining Service Access Points (SAPs)
d. Sequencing

802.3 is a group of IEEE standards which defines the Ethernet LAN protocols. Four data rates are currently defined for operation over optical fiber and twisted-pair cables:
10 Mbps—10Base-T Ethernet (IEEE 802.3)
100 Mbps—Fast Ethernet (IEEE 802.3u)
1000 Mbps—Gigabit Ethernet (IEEE 802.3z)
10 Gbps—10Gigabit Ethernet (IEEE 802.3ae).

IEEE 802.4 defines the media access control (MAC) layer for bus networks that use a token-passing mechanism (token bus networks). This is an application of the concepts used in token ring networks. The main difference is that the endpoints of the bus do not meet to form a physical ring. The IEEE 802.4 Working Group is disbanded.
Standard Organization: IEEE
Reference Document: IEEE 802.4
802.5 is an IEEE standard for Token Ring technologies where all stations are connected in a ring, and each station can directly hear transmissions only from its immediate neighbor. Permission to transmit is granted by a message (token) that circulates around the ring. Token Ring as defined in IEEE 802.5 is originated from the IBM Token Ring LAN technologies. Both are based on the Token Passing technologies. While they differ in minor ways, but they generally compatible with each other.
Standard Organization: IEEE
Reference Document: IEEE 802.5
802.6 is an IEEE standard which defines Distributed Queue Dual Bus (DQDB) protocol for Metropolitan Area Networks (MANs). DQDB is designed for data as well as voice and video transmission based on cell switching technology (similar to ATM). DQDB, which permits multiple systems to interconnect using two unidirectional logical buses, is an open standard that is designed for compatibility with carrier transmission standards such as SMDS, which is based on the DQDB standards.
