TCP/IP (Transmission Control Protocol/Internet Protocol). This suite includes foundational protocols for internetworking. IP handles addressing and routing data packets, and TCP provides reliable, connection-oriented communication. For example, when you download a file, TCP manages the reliable transfer of data segments, and IP ensures those segments are routed to your computer.
IP (Internet Protocol). This protocol, especially IPv4, defines the addressing and routing scheme for packets across networks. It assigns unique addresses to devices, like 192.168.1.10, and enables routers to forward packets to their correct destinations.
X.25. This is an older packet-switched networking protocol suite designed for Wide Area Networks (WANs). It provided reliable data transmission over less dependable analog phone lines through features like virtual circuits.
