The transport layer is responsible for error-free, end-to-end delivery of data from the source host to the destination host. It corresponds to the transport layer of the OSI model. The functions of the transport layer are:It facilitates the communicating hosts to carry on a conversation. It provides an interface for the users to the underlying network. It can provide for a reliable connection. It can also carry out error checking, flow control, and verification.

The transport Layer of the TCP/IP Model consists of various protocols that perform all the functions of the OSI model’s Application, Presentation and Session layers. This includes interaction with the application, data translation and encoding, dialogue control and communication coordination between systems.

Detailed explanation-1: -Layer 4: The Transport Layer The transport layer provides a total end-to-end solution for reliable communications. TCP/IP relies on the transport layer to effectively control communications between two hosts. When an IP communication session must begin or end, the transport layer is used to build this connection.
Detailed explanation-2: -The TCP/IP transport layer ensures that packets arrive in sequence and without error, by swapping acknowledgments of data reception, and retransmitting lost packets. This type of communication is known as end-to-end.
Detailed explanation-3: -The network layer uses network addresses (typically Internet Protocol addresses) to route packets to a destination node. The data link layer establishes and terminates a connection between two physically-connected nodes on a network. It breaks up packets into frames and sends them from source to destination.
