What is the purpose of a router in a network?

The purpose of a router in a network is to direct data packets between networks. Routers are essential components of network infrastructure because they manage traffic effectively, ensuring that data sent from one device reaches its intended destination on another network. This involves determining the best path for data transmission and forwarding packets accordingly.

When data is transmitted over a network, it is broken down into small units called packets. The router examines these packets, uses routing tables and protocols to understand where each packet should go, and then sends them through the most efficient route available. This capability allows multiple devices and networks to communicate seamlessly, making routers critical for internet connectivity and local area networks.

The other options describe different functionalities that do not pertain to the primary role of a router. For instance, connecting computers to printers is typically the role of a print server or switch, while converting analog signals to digital is handled by modems or digital signal processors. Storing network data is primarily the function of servers or storage devices, not routers. Therefore, the role of directing data packets distinctly defines the router's contribution to network operations.
