A set of rules that governs the connection of computer systems to the internet is ______.

• A. TCP (Transmission Control Protocol)/IP (Internet Protocol)
• B. FTP (File Transfer Protocol)/HTTP
• C. DNS (Domain Name System)
• D. SSH (Secure Shell)

Answer: (A)

TCP/IP is the foundational protocol suite for internet connections. IP handles addressing and routing, so data packets know where to go and how to reach any device on the network. TCP sits on top of IP to provide reliable communication: it establishes a connection, ensures data is delivered in order, checks for errors, and retransmits any lost packets. Together, these protocols define how systems connect, locate each other, and exchange data across the global network. The other options describe specific protocols that operate within this framework but do not set the overall rules for connectivity. FTP and HTTP are application-layer methods that use TCP/IP to transfer files or fetch web pages. DNS translates human-friendly names into IP addresses, aiding location but not establishing the connection rules themselves. SSH offers secure remote access, again relying on the TCP/IP stack but not defining the general connectivity framework.
