Detailed explanation-1: -Guided media, which are those that provide a conduit from one device to another, include twisted-pair cable, coaxial cable, and fiber-optic cable. A signal traveling along any of these media is directed and contained by the physical limits of the medium.
Detailed explanation-2: -Guided media is like a physical medium via which the signals are transmitted. The guided media is used to provide a conduit from one machine to another that can have twisted-pair, coaxial cable and fibre-optic cable. It is also known as Bounded media.
Detailed explanation-3: -Guided − In guided media, transmitted data travels through cabling system that has a fixed path. For example, copper wires, fibre optic wires, etc. Unguided − In unguided media, transmitted data travels through free space in form of electromagnetic signal. For example, radio waves, lasers, etc.
