Which type of network media carries data encoded into impulses of light?

  • coaxial cable
  • wireless media
  • fiber-optic cable
  • twisted-pair cable

Explanation: Data is transmitted across a network on media. Modern networks primarily use three types of media to interconnect devices:

  • Metal wires within cables (copper cable) - Data is encoded into electrical impulses. Twisted Ethernet cable and coaxial cable are two types of copper cable.
  • Glass or plastic fibers within cables (fiber-optic cable) - Data is encoded into pulses of light.
  • Wireless transmission - Data is encoded via modulation of specific frequencies of electromagnetic waves.
