Answer:

User Datagram Protocol (UDP) , transport-layer segment.

Explanation:

The User Datagram Protocol is popularly known as UDP. It is defined as the communication protocol which is used across the internet for any time sensitive transmission like the DNS lookup or the video playback.

The UDP provides a unreliable and connectionless service to a invoking application.

The transport layers on sending side converts the application $\text{layer }$ messages which it $\text{receives}$ from the $\text{sending application process}$ into a transport layer segment called as the transport layer segments. This is achieved by breaking down the application messages into a smaller chunks and then adding the transport layer header into each chunk so as to create a transport layer segment.

geniusboy [140]

Answer:

There are no additional components that can be added to the IPv4 protocol to improve its utility

Explanation:

The IPv4 protocol was developed in 1983 and is still the most widely used version worldwide. It consists of a 32-bit binary number that is normally represented in decimal notation, with four digits separated by dots that take values between 0 and 255.

This system limits the IPv4 protocol to 4,000 million different addresses, a figure that in the eighties seemed sufficient but that in practice has been scarce due to the revolution of mobile devices and the impending development of the Internet of Things ( IoT) that will trigger the number of devices connected to the network.

So, there are no additional components that can be added to the IPv4 protocol to improve its utility, since the world is running out of IPv4 addresses and is being replaced by IPv6.

Hope this helps!

  • In option a, It requires voluntary context switches in I /O bound.
  • In option b, it requires a non-voluntary context switch for CPU bound.
