Coaxial cable is a two-conductor cable in which one conductor forms an electromagnetic shield around the other.
Explanation:
A coaxial cable consists of many small cables in a protective cover. The cover shields the cable from physical dangers as well as from electromagnetic interference. Within the cover, the various cables are shielded from interference with one another. Coaxial cables are used in communication networks that require many simultaneous communication links. Each coaxial cable can provide more than 5000 links. It has a data rate of 10 Mbps which can be increased with the increase in diameter of the inner conductor. The specified maximum number of nodes on a thinnet segment is 30 nodes and on a thicknet it is 100 nodes.
Answer:
Coaxial cables are the guided media that carnes the signal of higher frequency range compared to twisted pair cable. Coaxial cables are also called coax. (short form). Two types of coaxial cables are widely used: 50 ohm cable and 75 ohm cable. 50 ohm cable is used for digital transmission and 75 ohm cable is used for analog transmission.
