What is the role of a router in a network?

• A. To host website services
• B. To direct data packets between devices and networks
• C. To monitor internet usage
• D. To enhance graphics quality on devices

Answer: (B)

The role of a router in a network is to direct data packets between devices and networks. Routers serve as critical junctions that manage traffic within networks, ensuring that data sent from one device reaches its intended destination efficiently. When data is transmitted over the internet or within any network, it is broken down into smaller packets. The router examines these packets and makes decisions about the best path for the data to travel, based on factors such as network congestion, destination addresses, and routing protocols.

This ability to route data effectively is what enables communication between multiple devices—such as computers, smartphones, and printers—within a local area network (LAN) and also allows these devices to connect with external networks, like the internet. In contrast, other roles described in the choices—such as hosting website services or enhancing graphics quality—are functions not typically associated with routers. Monitoring internet usage may be part of network management but is not the primary role of a router. Therefore, directing data packets accurately between devices is fundamental to the router’s function in a network.
