Explanation of Solution

Communication media:

  • Communication media refers to delivering and receiving data or information.
  • Transmission and storage tools or channels for data storage and transmission fall under telecommunication.
  • The transmission media can be divided into two categories guided transmission media and wireless transmission media.
  • The communications signals are guided along a solid medium in the guide transmission media. For example, twisted-pair wire, fiber-optic cable, coaxial cable.
  • The telecommunication signal is broadcast over airwaves in the wireless transmission media. The major technologies include microwave, infrared and radio.

Explanation for incorrect options:

Infrared and microwave

The infrared and microwave are the example of the wireless telecommunication media.

Hence, the option “A” is wrong.

Fiber optic and cable

The fiber optic and cable are the example of the guided telecommunication media.

Hence, the option “B” is wrong.

Packet switching and circuit switching

Packet switching and circuit switching are not the categories of communication media.

Hence, the option “C” is wrong.
