Network Wiring Definitions
Definitions copied from here:

- baseband
- The use of the entire bandwidth of the network cable to transmit a
single digital signal. The frames are applied directly to the cable in digital
form without modulation or multiplexing. Ethernet and Token Ring are Baseband
transmissions because they use only one protocol.
- BNC
- The Bayonet-Neill-Concelman connector. Widely used in 10BASE2 and other
thin coaxial applications. I always thought this was British Naval Connector.
- bridge
- In the LAN arena, it is a device used to connect two physically separate
networks. They may or may not have the same topology.
- CARRIER SENSE MULTIPLE ACCESS/COLLISION DETECTION
- CSMA/CD. The most common form of access control found in an ethernet environment. It is used to avoid data collisions in a logical bus topology, like Ethernet .
- CAT 3
- 4 Pair UTP cable and associated connecting hardware whose transmission characteristics are specified up to 16 MHz.
(TIA/EIA; SEE ISO 11801 CLASSES A, B, C) - CAT 4
- 4 Pair UTP cable and associated connecting hardware
whose transmission characteristics are specified up to 20 MHz.
(TIA/EIA; SEE ISO 11801 CLASSES A,B,C) - CAT 5
- 4 Pair UTP cable and associated connecting hardware
whose transmission characteristics are specified up to 100 MHz.
(TIA/EIA; SEE ISO 11801 CLASS D) - CAT 5E
- 4 Pair UTP cable and associated connecting hardware
whose transmission characteristics are specified up to 100 MHz.
Has approximately 3dB stronger signal strength than standard CAT 5.
(TIA/EIA; See ISO 11801 Class E) - CAT 6
- 4 Pair UTP cable and associated connecting hardware
whose transmission characteristics are specified up to 200 MHz.
(TIA/EIA; See ISO 11801 Class E) - CAT 7
- 4 Pair STP cable and associated connecting hardware
whose transmission characteristics are specified up to 600 MHz.
(TIA/EIA; SEE ISO 11801 CLASS F)
