Guided transmission mediums are communication channels that have a defined physical path for the transmission of signals. These mediums include cables and wires such as twisted pair cables, coaxial cables, and optical fibers. The physical pathway ensures that the signal is directed along a specific route from the sender to the receiver, providing a controlled and reliable means of communication. This contrasts with unguided transmission mediums, such as radio waves or satellite signals, which broadcast signals over the air without a defined path. The use of guided transmission mediums helps in reducing signal loss and interference, improving the overall quality and efficiency of data transmission.
