Communication Systems - ECE Questions and Answers

The representation of data can be done through computers as well as other types of telecommunication devices with the help of signals. These are broadcasted from one device to another in the shape of electromagnetic energy. The signals like electromagnetic can travel throughout vacuum, air otherwise other transmission mediums to travel from one sender to another receiver. In the OSI model, the first layer is the physical layer which is dedicated to the transmission media. Definition: A communication channel that is used to carry the data from the transmitter to the receiver through the electromagnetic signals.

Objective Questions on Data Transmission Medium Part-1

Explanation: The RSC is a standard interface for serial data transmission that defines the protocol and physical interface for transmitting serial data fairly easily between associated appliances and computers. Explanation: The star topology is the best network topology for large businesses because it is simple to control and coordinate from the central computer. Explanation: Double duplex is not a legitimate channel for transmission in computer network. Explanation: The parity bit is also known as the check bit, and has a value of 0 or 1. It is used for error detection for blocks of data. Explanation: The optical fiber is made of glass or plastic.

This Data Communication and Networking – Transmission Media Multiple choice Questions and Answers (MCQ) PDF covers the below lists of topics.

Transmission Media

For any networking to be effective, raw stream of data is to be transported from one device to other over some medium. Various transmission media can be used for transfer of data. For example, copper wires, fibre optic wires, etc. For example, radio waves, lasers, etc. Each transmission media has its own advantages and disadvantages in terms of bandwidth, speed, delay, cost per bit, ease of installation and maintenance, etc.

What is Transmission Media in Computer Networks & Its Types

Transmitter, receiver, transmission medium — these are the basic elements that make up a communication system. Every human being is equipped with a basic communication system. The mouth and vocal cords is the transmitter, ears are the receivers, and air is the transmission medium over which sound travels between mouth and ear. The transmitter and receiver elements of a data modem such as the type used in a traffic signal system controller box may not be readily visible.

By Practicing these interview questions, you can easily crack any Competitive Exams interview. Fully solved examples with detailed answer description. In Line communication, signals are directly transmitted through the transmission lines. The installation and maintenance of a transmission line is not only costly and complex, but also overcrowds the open space. In Radio communication, signals are transmitted by using antenna through the free space in the form of EM waves.
