Explanation:
coaxial
Coaxial cable,Waveguide and Fibre optic cable is an example of bounded medium.
The physical channels (the media) that carry data are of two types: bounded and unbounded. In a bounded medium, the signals are confined to the medium and do not leave it (except for smaller leakage amounts). A pair of wires, coaxial cable, waveguide, and optical-fiber cable are examples of bounded media.
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.
A waveguide is an electromagnetic feed line used in microwave communications, broadcasting, and radar installations. A waveguide consists of a rectangular or cylindrical metal tube or pipe. The electromagnetic field propagates lengthwise. Waveguides are most often used with horn antenna s and dish antenna s.
Fiber optics, or optical fiber, refers to the medium and the technology associated with the transmission of information as light pulses along a glass or plastic strand or fiber. A fiber optic cable can contain a varying number of these glass fibers -- from a few up to a couple hundred.
