Detailed explanation-1: -The transport layer is Layer 4 of the Open Systems Interconnection (OSI) communications model. It is responsible for ensuring that the data packets arrive accurately and reliably between sender and receiver. The transport layer most often uses TCP or User Datagram Protocol (UDP).
Detailed explanation-2: -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-3: -Packets are data units within the network layer in the OSI model.
Detailed explanation-4: -Transport layers (Layer 4) work transparently within the layers above to deliver and receive data without errors. The send side breaks application messages into segments (packets) and passes them on to the network layer (Layer 3).
