What is the role of transmission medium in a computer network?

What is transmission medium in computer network?

Computer NetworkComputer EngineeringMCA. 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 the role of transmission medium in a computer network give example?

Transmission medium is the physical path through which the message travels from the sender to the receiver. Twisted pair cable, coaxial cable, fibre optic cable and radio waves are some examples of transmission medium.

What is the role of communication media in computer network?

Communication media refers to the means of delivering and receiving data or information. In telecommunication, these means are transmission and storage tools or channels for data storage and transmission.

What is the transmission medium used in this type of network?

Guided transmission media are cables like twisted pair cables, coaxial cables, and fiber optic cables. Unguided transmission media are wireless, such as infrared, radio waves, and microwaves. Connectors are used to connect the media with networking devices, and they are specific for each transmission medium.

What is the biggest advantage 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 of these is an example of unguided transmission?

Examples of this include microwave, radio or infrared. Unguided media provide a means for transmitting electromagnetic waves but do not guide them; examples are propagation through air, vacuum and seawater.

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 are the two major types of communication media?
