In data communication terminology, a transmission medium is a physical path between the transmitter and the receiver i.e it is the channel through which data is sent from one place to another.
What is transmission medium and its types?
Transmission media acts a physical interface for communication in networks. There are two types of transmission media, namely guided and unguided. Guided transmission media are cables like twisted pair cables, coaxial cables, and fiber optic cables.
What is transmission medium give examples?
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.
What do you mean by transmission medium differentiate between guided and unguided transmission media?
The key difference between guided and unguided media is that guided media uses a physical path or conductor to transmit the signals whereas, the unguided media broadcast the signal through the air. The guided media is also called wired communication or bounded transmission media.
What is the transmission medium in WIFI connection?
Types of wireless transmission media used in communications include infrared, broadcast radio, cellular radio, microwaves, and communications satellites. As discussed earlier in the chapter, infrared (IR) is a wireless transmission medium that sends signals using infrared light waves.
Which is not a medium of transmission?
Microwave System is not a transmission medium rather than it other options is used for transmission of data over a cables as well as lines.
Which type of transmission medium is appropriate for such a link?
(e4) The most economic way to connect it with a reasonable high speed would be to use radio wave transmission, as they are easy to install, can travel long distances, and penetrate buildings easily, so they are widely used for ommunication, both indoors and outdoors.
What are the criteria used to evaluate transmission medium?
Factors to consider when choosing transmission media include: cost, ease of installation and maintenance, availability, and most important, efficiency of transmission. Transmission efficiency is generally viewed as the amount of signal degradation created by the use of a particular transmission medium.
What is the example of unguided media?
Unguided transmission media are methods that allow the transmission of data without the use of physical means to define the path it takes. Examples of this include microwave, radio or infrared.
