what is the use of coaxial cable
Answers
Explanation:
Coaxial cable, or coax (pronounced /ˈkoʊ.æks/) is a type of electrical cable that has an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conducting shield. Many coaxial cables also have an insulating outer sheath or jacket. The term coaxial comes from the inner conductor and the outer shield sharing a geometric axis. Coaxial cable was invented by English physicist, engineer, and mathematician Oliver Heaviside, who patented the design in 1880.[1]
Coaxial cable is a type of transmission line, used to carry high frequency electrical signals with low losses. It is used in such applications as telephone trunklines, broadband internet networking cables, high speed computer data busses, carrying cable television signals, and connecting radio transmitters and receivers to their antennas. It differs from other shielded cables because the dimensions of the cable and connectors are controlled to give a precise, constant conductor spacing, which is needed for it to function efficiently as a transmission line.

Answer:
A coaxial cable us used in the transmission of video , communication ,and audio. it is mainly used by the cable television industry to connect TVs to a cable TV service. However, this cable can also be used in networks and has high bandwidth and greater transmission capacity. A Coaxial cable consists of central copper wire surrounded by insulation and then a shield of braided wire. The two main types of coaxial cable are:
Baseband Coaxial cable: it supports quick transmission of a single signal at a time . it is mainly used for LANs.
broadband coaxial cable : it transmits multiple signals at the same time and is used for longer distances .
