| Media Access Control | Lower of the two sublayers of the data link layer defined by the IEEE. The MAC sublayer handles access to shared media, such as whether token passing or contention will be used. |
| Physical Layer Protocol | One of two sublayers of the FDDI physical layer. |
| Physical Layer Medium | Sublayer of the FDDI physical layer that interfaces directly with the physical medium and performs the most basic bit transmission functions of the network. |
| Station Management | ANSI FDDI specification that defines how ring stations are managed. |
| token-ring refers | both, to IBM's token-ring and to IEEEs 802.5 specification |
| FDDI has four specifications, Those four main points are | MAC,PHY,PMD,SMT, |
| Ethernet is often used to refer | all carrier sense multiple access/collision detection (CSMA/CD) LAN’s that generally conform to Ethernet specifications, including IEEE 802.3 |
| Layer 2 devices and their effects on | data flow |
| Basic Ethernet | 10BASE-T Troubleshooting |
| Basics of Fiber Distributed | Data Interface (FDDI) |
