Answer:
d. data packets
Step-by-step explanation:
A router is a networking device that connects multiple networks together and passes data packets between them. A data packet is a unit of data that is transmitted over a network. When a computer sends data to another computer on a different network, the data is divided into packets, and each packet contains information about the source and destination of the data. The router reads this information and decides where to send each packet based on the destination address. The packets may need to pass through several routers before reaching their final destination. Routers use routing tables and algorithms to determine the best path for the data packets to take.
