Detailed explanation-1: -Coaxial cable and twisted pair cable are copper-based cables protected by insulating and shielding materials. They both transmit television, telephone, and data through electrical signals, whereas fiber optic cables use light to transmit similar types of signals.

Detailed explanation-2: -They are coaxial cable, twisted-pair, satellite, fiber optics & microwave, Thus, this is all about transmission media and there are some factors that are considered when choosing a transmission Medium like rate of transmission, cost, simple installation, and distances.

Detailed explanation-3: -There are two methods used to transmit data between digital devices: serial transmission and parallel transmission. Serial data transmission sends data bits one after another over a single channel. Parallel data transmission sends multiple data bits at the same time over multiple channels.
