How do guided media differ from unguided media? What are the three major classes of guided media? Name the advantages of optical fiber over twisted-pair and coaxial cable?

Answer»

Answer:

GUIDED media and unguided media, both terms are related to computer networking, there are mainly TWO medium through which transmission of data takes place. Guided and unguided media, also known as wired and wireless mode of transmission.

Explanation:

  • Guided media has lesser noise and obstacles in comparison to unguided media, this causes guided media to give a faster rate of data transmission than unguided media.
  • OPTICAL FIBERS are very costly but FASTEST mode of data transmission. The reason for this is because the data travels with the speed of light in optical fiber, as the data sent and received is done by passing light through cable.
  • Twisted pair cable are also a medium for transferring data, but they are sent as an analog signal, so it is not as fat as optical fibers.
