802.11 Wireless networking
802.12 100 Mbps technologies (includes 100BASEVG-AnyLAN)
If you plan to take the CompTIA Network+ exam, you need to be familiar with the 802.2, 802.3, 802.5, and 802.11b standards. (Explained below)
802.2 IEEE Standard
-LLC (Logical Link Control) sublayer of the OSI model
- Manages data flow control and error control
802.3 IEEE Standard
-Defines characteristics for Ethernet networks
- Original 802.3 standard defined a speed of 10Mbps. There are now faster Ethernet technologies, including Fast Ethernet and Gigabit Internet
-Original 802.3 standard specified coaxial and twisted pair cabling
-Ethernet networks use CSMA/CD (Carrier Sense Multiple Access with Collision Detection)
802.5 IEEE Standard
- Defines characteristics for Token Ring networks
- Token Ring networks introduced by IBM in mid-1980s
- Original standard specified speeds of 4 and 16Mbps
- Token Ring networks use twisted pair cabling and shielded twisted pair cabling
-Uses and access method called token passing
802.11b IEEE Standard
- Defines standards of wireless LAN Ethernet
- Standard speed of 11Mbps
- Uses a physical wireless topology with a logical bus topology
