In the OSI (Open Systems Interconnection) model, the transport layer (Layer 4) is responsible for providing connection-oriented and reliable communication. Protocols like TCP (Transmission Control Protocol) establish a connection between sender and receiver, ensuring data is delivered accurately and in order. This is achieved through mechanisms such as error detection, retransmission of lost packets, and flow control, which manage the rate of data transmission to prevent congestion. In contrast, connectionless protocols like UDP (User Datagram Protocol) do not guarantee delivery, order, or reliability.
