A router is one of the most common communication devices used in networking.
Step 1: Analyzing each option.
• USB Drive A USB drive stores and transfers files. It is a storage device, not a communication device. Hence, incorrect.
• Monitor A monitor displays visual output. It is an output device. Hence, incorrect.
• Printer A printer produces hard copies of documents. It is an output device. Hence, incorrect.
• Router A router directs and forwards data packets between different networks. It enables communication among devices and provides internet connectivity. Hence, correct.
Step 2: Final conclusion. The only communication device among the given options is the router. Therefore, \[ \boxed{\text{Router}} \] is the correct answer.
