In network terminology, what device translates information from one protocol to another?

• A. ROUTER
• B. BRIDGE
• C. FPGA
• D. GATEWAY

Answer: (D)

Translating information from one protocol to another is what a gateway does. A gateway acts as a translator between networks that use different protocols or data formats, allowing devices on one side to communicate with systems on the other. Routers forward packets based on IP routing within a network family, and bridges connect similar network segments without changing protocols, so they don’t perform broad protocol translation. An FPGA is a programmable hardware platform that can implement a variety of functions, including translation, but it isn’t defined by default as a network translator. So the device whose primary role is translating between protocols is the gateway.
