What does a router do in a home network?

A router plays a crucial role in a home network by directing data packets between different devices and the internet. It acts as a traffic manager, ensuring that data sent from your devices (like computers, smartphones, or smart TVs) is appropriately routed to the intended destination, whether that be another device on the local network or a server on the internet.

When data is transmitted over the internet, it is divided into smaller packets. The router examines these packets and uses routing tables and protocols to determine the best path for each packet. This efficient handling of data ensures that communications are timely and that bandwidth is utilized effectively.

In contrast to this function, managing WiFi connections pertains specifically to the radio frequency and connectivity aspect of the network, which is just one part of what routers do. Translating signals from an Internet Service Provider (ISP) into usable internet data is a function often handled by a modem, which works closely with the router. Lastly, while some routers might have built-in storage capabilities, the primary function is not to store files but rather to route data between devices, distinguishing the main purpose of a router in network architecture.
