Detailed explanation-1: -Physical transmission media used in communications include twisted-pair cable, coaxial cable, and fiber-optic cable. These cables typically are used within or underground between buildings. Ethernet and token ring LANs often use physical transmission media.
Detailed explanation-2: -The common transmission mediums for traditional low-speed LANs are coaxial cable and twisted pairs. High-speed backbone LANs advocate the use of the optical fiber.
Detailed explanation-3: -LAN(Local Area Network) Generally, it is used to connect two or more personal computers through a communication medium such as coaxial, twisted-pair cables, etc. A LAN can use either wired or wireless mode of communication.
Detailed explanation-4: -In comparisons between coax vs twisted pair, coaxial cables are able to transmit over 80 times the amount of data as a twisted pair cable. Because of this, coaxial cables are almost always used for high-speed communication, including internet, cable and telecommunications services.
