Detailed explanation-1: -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: -In terms of the OSI model, TCP is a transport-layer protocol. It provides a reliable virtual-circuit connection between applications; that is, a connection is established before data transmission begins.
Detailed explanation-3: -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. It facilitates the communicating hosts to carry on a conversation.
Detailed explanation-4: -As mentioned earlier, TCP is the most common transport layer protocol. It is used by many application layer protocols like the HyperText Transfer Protocol (HTTP) and FTP.
Detailed explanation-5: -The transport layer is the fourth layer in the open systems interconnection (OSI) network model. The OSI model divides the tasks involved with moving information between networked computers into seven smaller, more manageable task groups. Each of the seven OSI layers is assigned a task or group of tasks.
