What layer of the OSI model is responsible for data transport?

The Transport Layer of the OSI model is responsible for data transport, ensuring that data is transferred from one point to another reliably and efficiently. This layer provides critical services such as segmentation, which divides larger messages into smaller packets for easier transmission and reassembly at the destination. It also establishes, maintains, and terminates connections between devices, enabling reliable communication through error detection, correction, and flow control mechanisms.

In addition to these functions, the Transport Layer operates independently of the underlying network architecture, allowing compatibility with various network technologies. It encompasses protocols like TCP (Transmission Control Protocol) for reliable communication with acknowledgments, and UDP (User Datagram Protocol) for connectionless communication with speed prioritized over reliability. This versatility makes the Transport Layer crucial for effective data transport in networking scenarios.
