Why do we use transmission media?

Transmission media is a communication channel that carries the information from the sender to the receiver. … The main functionality of the transmission media is to carry the information in the form of bits through LAN(Local Area Network). It is a physical path between transmitter and receiver in data communication.

What is meant by transmission media?

The transmission medium can be defined as a pathway that can transmit information from a sender to a receiver. Transmission media are located below the physical layer and are controlled by the physical layer. Transmission media are also called communication channels.

What is transmission media example?

Describes the type of physical system used to carry a communication signal from one system to another. Examples of transmission media include twisted-pair cable, coaxial cable, and fiber optic cable.

Which transmission media is best and why?

Optical fibers are the most secure of all the cable media. Installation and maintenance are difficult and costly. Fiber optic cables have greater transmission speed, high bandwidth, and the signal can travel longer distances when compared to coaxial and twisted pair cables.

Which are the common transmission media used in digital communication?

Which are the common transmission media used in digital communication system? Explanation: Some of the commonly used physical transmission media are twisted copper cable, good quality coaxial cable and radio frequency bands.

What are some examples of transmission?

An example of transmission is when something travels over cable wires to get to its destination. An example of the transmission of a virus is when a person spreads a cold virus by sneezing on someone else. Something that is transmitted, such as a message, picture or a disease; the sending of such a thing.

What are the most common transmission media used in homes?

Twisted copper pair, is what Alexander Bell used to make the first telephone system work and is generally the most common transmission medium used today. A broad generalization is that twisted copper pair is in fact the basis for all telecommunication technology and services today.

What is another name for transmission media?

The physical means by which data is transmitted from one geographic or electronic location to another is called transmission, or “communication” media.

What is transmission in data communication?

Data transmission is the transfer of data from one digital device to another. This transfer occurs via point-to-point data streams or channels. These channels may previously have been in the form of copper wires but are now much more likely to be part of a wireless network.

What are two advantages of networking?

Advantages and disadvantages of networks

Files can easily be shared between users. Network users can communicate by email and instant messenger . Security is good – users cannot see other users’ files unlike on stand-alone machines. Data is easy to backup as all the data is stored on the file server .

Which transmission media are widely used in the backbone of network?

Coaxial cable has, in the past, been used to provide network backbone cable segments. Coaxial cable has largely been replaced in computer networks by optical fibre and twisted pair cable, with fibre used in the network backbone, and twisted pair used to connect workstations to network hubs and switches.

What are the main features of a transmitter?

What are the main features of a transmitter? Explanation: Some of the main features which make the transmitter complex are higher clock speed, higher transmit power, directional antennas and need for a linear amplifier.

Why spread spectrum is required?

The main advantage of spread spectrum communication technique is to prevent “interference” whether it is intentional or unintentional. The signals modulated with these techniques are hard to interfere and cannot be jammed. … These spread spectrum signals transmit at low power density and has a wide spread of signals.

Which process is more economical in digital communication?

Which process is more economical? Explanation: Oversampling is most economic way of sampling or for converting analog information to digital as performing signal processing using digital system is less costlier than doing it with high performace analog system.
