MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Radio waves’ are electromagnetic waves used in different forms of wireless communication such as television, radios, and mobile phones. These devices convert the microwave radio waves mechanical vibrations in the speaker to make sound waves.

Detailed explanation-2: -Microwave radio transmission is commonly used in point-to-point communication systems on the surface of the Earth, in satellite communications, and in deep space radio communications. Other parts of the microwave radio band are used for radars, radio navigation systems, sensor systems, and radio astronomy.

Detailed explanation-3: -Radio waves are used for communication such as television and radio. Radio waves are transmitted easily through air. They do not cause damage if absorbed by the human body, and they can be reflected to change their direction. These properties make them ideal for communications.

Detailed explanation-4: -Radio waves are used for wireless transmission of sound messages, or information, for communication, as well as for maritime and aircraft navigation. The information is imposed on the electromagnetic carrier wave as amplitude modulation (AM) or as frequency modulation (FM) or in digital form (pulse modulation).

Detailed explanation-5: -Fixed Wireless is communication between multiple points of presence that utilizes Microwave RF to transmit high-speed data. These frequencies permit high bandwidth and low latency, which increases end user productivity.
