TCP/IP stands for which combination of protocols?

• A. Transmission Control Protocol
• B. Uniform Resource Locator
• C. Universal Serial Bus
• D. Transmission Control Protocol/Internet Protocol

Answer: (D)

TCP/IP is a suite of network protocols that work together to enable communication over networks. The acronym stands for Transmission Control Protocol and Internet Protocol—the two foundational protocols that define how data is packaged, addressed, transmitted, and reassembled. IP is responsible for addressing packets and routing them to the destination, while TCP provides reliable delivery with sequencing and error checking. The other options describe either a single protocol (Transmission Control Protocol), a web address format (Uniform Resource Locator), or a hardware interface (Universal Serial Bus), none of which capture the full pairing that TCP/IP represents.
