Which term describes the suite of protocols used to connect and transmit data over the Internet?

• A. Transmission Control Protocol/Internet Protocol (TCP/IP)
• B. Transmission Media
• C. Transport Layer
• D. Trivial File Transfer Protocol (TFTP)

Answer: (A)

The TCP/IP protocol suite is the set of rules that governs how devices connect and exchange data across the Internet. It defines how data is broken into packets, addressed, routed from source to destination, and reassembled at the end. This suite combines the Internet Protocol (IP) for addressing and routing with the Transmission Control Protocol (TCP) for reliable, connection-oriented delivery, along with many other protocols that handle different parts of communication (like DNS for naming, HTTP for web traffic, and ICMP for error messages). Because it covers the entire process of interconnecting networks and moving data between devices worldwide, TCP/IP is the standard framework used to connect and transmit data over the Internet. Transmission media refers to the physical path data travels, the Transport Layer is just one layer within the model, and TFTP is a single protocol for file transfer, not the whole suite.
