Which of the following is used to provide the service of exchanging data directly between two hosts on the same network?

STP (Spanning Tree Protocol) operates at Layer 2 to prevent switching loops in Ethernet networks and plays no role in delivering data between hosts.

UDP is a connectionless, best-effort transport protocol that does not establish a session or guarantee delivery, so it does not provide reliable direct data exchange between hosts.

TCP (Transmission Control Protocol) operates at Layer 4 and uses a three-way handshake to establish a direct, reliable connection between two hosts before any data is transferred. It guarantees delivery, correct ordering, and error detection, making it the standard protocol for dependable host-to-host data exchange on the same or different networks.

SNMP (Simple Network Management Protocol) is used to monitor and manage network device status and statistics, not to exchange application data between hosts.
