A. B. C. D.Answer - B.
The Transport layer (also known as the Host-to-Host Transport layer) is responsible for providing the Application layer with session and datagram communication services.
The core protocols of the Transport layer are Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP).
For more information on the TCP IP Model, one can visit the below URL:
https://technet.microsoft.com/en-us/library/cc958821.aspxThe TCP/IP model is a conceptual framework used for communication between devices in a network. It has four layers:
Each layer provides a specific set of services to the layers above it and makes use of the services provided by the layers below it.
The Transport Layer is responsible for ensuring reliable data delivery between two endpoints. It uses two core protocols: Transmission Control Protocol (TCP) and User Datagram Protocol (UDP).
TCP provides reliable, ordered, and error-checked delivery of data between applications running on hosts communicating over an IP network. It establishes a connection between the sender and receiver before data is exchanged and manages the flow of data between them. TCP is connection-oriented, meaning that it establishes a connection before data is sent and ensures that all data is received correctly by the receiver.
UDP, on the other hand, is a connectionless protocol that is used when speed is more important than reliability. It does not establish a connection before data is sent and does not provide any reliability or error-checking mechanisms.
Therefore, the Transport Layer is the layer that makes use of the core protocols of TCP and UDP.
In conclusion, the correct answer to the question is B. Transport Layer.
