The role of a router in a network is to manage connections between separate networks. Routers operate by receiving data packets from one network and directing them to another, ensuring that information is sent to the correct destination. This is essential in larger networks, such as the internet, where devices on different networks need to communicate with one another. Routers use routing tables and protocols to determine the most efficient path for data to travel, allowing for reliable and organized communication across diverse and geographically dispersed networks.

In contrast, storing large amounts of data is primarily the function of servers or storage devices, while providing internet access to local devices is a task usually handled by a modem combined with a router in a home network setup. The conversion of digital signals to analog is associated with modems, which is necessary for communication over traditional phone lines. Thus, the main purpose of a router distinctly aligns with managing the interconnection of different networks, making it crucial for the overall functionality of data communication.
