So the MCQs on this topic is very helpful for the students to prepare for their exams, interviews, etc to gain knowledge on the Broadband communication concept. Generally, a Broadband communication system provides channels for the transmission of data within several directions by many users. For instance, the coaxial CATV is a broadband communication system that transmits several TV channels over a similar cable and also handles data transmissions within a completely different frequency spectrum. Typical broadband communication systems are ATM, ISDN, frame relay, leased lines & T carriers, DSL, cable data networks, and wireless communications. Broadband is high-speed-based Internet access that is always faster as compared to the usual dial-up access. A broadband connection mainly includes different high-speed transmission technologies like fiber, wireless, digital subscriber line, satellite, broadband over power lines, etc. Broadband communication is mainly used for browsing, communication between person to person, voice services, entertainment, public services, etc. 1).
