In which layer of the OSI model is a TCP protocol located?

Network layer
Physical layer
Data Link layer
Session layer

The correct answer is: Network layer

The TCP protocol is located in the Network layer of the OSI model because it deals with routing and logical addressing. The physical layer (B) deals with the physical transmission of data, the Data Link layer (C) provides a reliable connection between two nodes, and the Session layer (D) manages the communication sessions between two devices. Therefore, A is the most suitable layer for TCP, as it is responsible for managing the movement of data packets within a network.
