Problem Statement
Differentiate between guided and unguided transmission media with examples.
Explanation
Guided media use a physical path to transmit data signals, such as copper wires or fiber-optic cables. Examples include twisted pair, coaxial, and optical fiber. They are reliable and less prone to interference. Unguided media, on the other hand, use air, water, or vacuum as the transmission medium. Examples include radio waves, microwaves, and infrared. They are flexible and support mobility but are more susceptible to interference and signal loss. Mentioning trade-offs between cost, speed, and range strengthens your interview answer.
