Network Media and Connectors / Internet and Networking

• Cabling is the LAN's transmission medium. 
• Three primary types of physical media can be used: coaxial cable,  twisted - pair cable,  and fiber-optic cable. 
• Coax uses a copper core that carries an electrical signal.  There are two types of coax: thinnet and Thicknet.  Hosts connect to thinnet through BNC connectors,  whereas vampire taps and drop cables are used to connect to Thicknet. 
• Twisted - pair cabling is a cable type similar to telephone cable,  but there are right wires instead of four.  Telephone cable use an RJ - 11 connector,  whereas network cabling used an RJ -45 connector. 
• Fiber - optic cabling has a glass or clear - plastic core that carries pulses of light.  The straight tip (ST)  and subscribe connector (SC)  are connector used with fiber-optic cabling.
