Question

Below figure represents the mechanism used by the T-1 service to transmit data using _________ technology at the physical layer. 
A) Modulation 
B) Multiplexing 
C) Asynchronous transmission 
D) Broadband 
E) Spread spectrum

Quizplus · Accepted Answer

The figure shows that multiple data streams are being combined into one signal for transmission, which is a characteristic of multiplexing technology at the physical layer. Modulation refers to the process of encoding digital signals onto a carrier wave, while asynchronous transmission is a communication method that does not use a clock signal. Broadband refers to a wide range of frequency bands, and spread spectrum is a method of transmitting signals across multiple frequencies to improve reliability and security.
