| 802 | Overview | Basics of physical and logical networking concepts. |
| 802.1 | Bridging | LAN/MAN bridging and management. Covers management and the lower sub-layers of OSI Layer 2, including MAC-based bridging (Media Access Control), virtual LANs and port-based access control. |
| 802.2 | Logical Link | Commonly referred to as the LLC or Logical Link Control specification. The LLC is the top sub-layer in the data-link layer, OSI Layer 2. Interfaces with the network Layer 3. |
| 802.3 | Ethernet | "Grandaddy" of the 802 specifications. Provides asynchronous networking using "carrier sense, multiple access with collision detect" (CSMA/CD) over coax, twisted-pair copper, and fiber media. Current speeds range from 10 Mbps to 10 Gbps. |
| 802.4 | Token Bus | Disbanded |
| 802.5 | Token Ring | The original token-passing standard for twisted-pair, shielded copper cables. Supports copper and fiber cabling from 4 Mbps to 100 Mbps. Often called "IBM Token-Ring." |
| 802.6 | Distributed queue dual bus (DQDB) | "Superseded **Revision of 802.1D-1990 edition (ISO/IEC 10038). 802.1D incorporates P802.1p and P802.12e. It also incorporates and supersedes published standards 802.1j and 802.6k. Superseded by 802.1D-2004." |
| 802.7 | Broadband LAN Practices | Withdrawn Standard. Withdrawn Date: Feb 07, 2003. No longer endorsed by the IEEE. |
| 802.8 | Fiber Optic Practices | Withdrawn PAR. Standards project no longer endorsed by the IEEE. |
| 802.9 | Integrated Services LAN | Withdrawn PAR. Standards project no longer endorsed by the IEEE. |
| 802.10 | Interoperable LAN security | Superseded **Contains: IEEE Std 802.10b-1992. |
| 802.11 | Wi-Fi | Wireless LAN Media Access Control and Physical Layer specification. 802.11a,b,g,etc. are amendments to the original 802.11 standard. Products that implement 802.11 standards must pass tests and are referred to as "Wi-Fi certified." |
| 802.11a |

Warchalking is a term that describes the act of walking around with a laptop, picking up locations of wireless access points, and drawing symbols to mark various information about the wireless access points. The term was coined in London of June of 2002 by Matt Jones
and a group of friends who used hobo-inspired symbols with chalk to mark various attributes to the wireless access points they encountered. He later posted the symbols on his blog and they became well known. The symbols - seen below each represent different descriptions of these WAPs.
The first symbol, on the left, represents an open Wireless Access Point. Anyone
