Which term refers to standards that ensure interoperability across hardware and software from different vendors?

• A. Switches
• B. Layer 8
• C. Network standards
• D. Host based architecture

Answer: (C)

Standards that define how systems communicate, exchange data, and behave across different vendors are called network standards. These rules cover protocols, data formats, addressing, and behaviors so equipment and software from various manufacturers can work together smoothly. Examples like TCP/IP, Ethernet, and Wi‑Fi illustrate how shared specifications enable interoperability in real networks.

The other options describe things that aren’t about shared communication rules: a switch is a hardware device, not a standard; Layer 8 is an informal joke about the human or organizational element rather than a formal standard; and host based architecture refers to where processing happens, not to the rules that enable cross-vendor compatibility.
