Question

Transport layer enables:

a.Different applications to access different physical media

 

b.Different applications to use different types of communication (reliable/unreliable)

 

c.Different applications to use different IP addresses

 

d.One application to access different physical media

​

Answer 1

Answer:

A. Examples of physical media include twisted-pair copper wire, coaxial cable, multimode fiber optic cable, terrestrial radio spectrum and satellite radio spectrum. Physical media fall into two categories: guided media and unguided media.

B. A reliable service is one that notifies the user if delivery fails, while an unreliable one does not notify the user if delivery fails. ... Together, Transmission Control Protocol (TCP) and IP provide a reliable service, whereas User Datagram Protocol (UDP) and IP provide an unreliable one.

C. Each device on the network will have its own IP address. However, not all devices use IP. Your Bluetooth devices like headphones or Fitbits don't (usually) use IP and they use a different, local type of address.

D. Examples of physical media include twisted-pair copper wire, coaxial cable, multimode fiber optic cable, terrestrial radio spectrum and satellite radio spectrum. Physical media fall into two categories: guided media and unguided media.

Answer 2

Answer:

Given below is the answer

Explanation:

A. Twisted-pair copper wire, coaxial cable, multimode fibre optic cable, terrestrial radio spectrum, and satellite radio spectrum are a few examples of physical media. Physical media can be divided into directed and unguided categories.

B. An unreliable service does not alert the user when delivery is unsuccessful, whereas a dependable one does. User Datagram Protocol (UDP) and IP provide an unreliable service, while Transmission Control Protocol (TCP) and IP give a reliable one.

C. Every networked device will have a unique IP address. But not all gadgets use IP. Your Bluetooth gadgets, such headphones or Fitbits, utilise a different, local sort of address instead of IP (typically).

D. Physical media examples include twisted-pair terrestrial radio spectrum, coaxial cable, multimode fibre optic cable, and satellite radio spectrum. Physical media can be divided into directed and unguided categories.
