Transmission Medium
A transmission medium could be a guided hard-wired medium (e.g., the twisted pair cable used in the telephone network), a coaxial cable used by CATV, or optical fiber.

Transmission Media
Unguided media (or wireless communication) transport electromagnetic waves without using a physical conductor. Instead, signals are broadcast through air (or, in a few cases, water), and thus are
