TCP and UDP belong to which protocol category?

Explanation:
TCP and UDP are transport-layer protocols. The transport layer handles end-to-end communication between processes on different hosts. TCP provides reliable, connection-oriented delivery with sequencing and flow control, while UDP offers a lightweight, connectionless datagram service. These roles are distinct from other layers: data-link deals with node-to-node transfer on a local link (frames and MAC addresses), network handles routing and IP addressing, and the application layer contains protocols used directly by software applications (like HTTP or DNS). So the category that fits TCP and UDP is the transport layer.
