Description: The transport layer is the fourth layer of the OSI (Open Systems Interconnection) model, responsible for end-to-end communication between systems. Its main function is to ensure that data is transmitted reliably and in the correct order, providing services such as data segmentation, flow control, and error correction. This layer uses protocols like TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) to manage data delivery. TCP is known for its focus on reliability, ensuring that data packets reach their destination without loss and in the correct order, while UDP is lighter and used in applications where speed is more critical than reliability, such as video streaming or online gaming. The transport layer also handles establishing, maintaining, and terminating connections between applications, making it an essential component for communication in modern networks. Its relevance extends to various platforms and technologies, including cloud computing and mobile networks, where efficient communication management between applications and services is crucial.
