Computer Network MCQ
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. For instance, in a copper cable network the bits in the form of electrical signals whereas in a fiber network, the bits are available in the form of light pulses.

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.
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.
