What does a router do?

Rationale

Manages traffic by maintaining a table of known devices on the network.

A router is primarily responsible for directing data traffic between devices on a network by maintaining a routing table. This table keeps track of known devices and their IP addresses, allowing the router to efficiently forward data packets to the correct destination.

A (Provides services, such as website hosting and routing, for various devices) YOUR ANSWER

While routers do facilitate routing for various devices, they do not typically provide services like website hosting. Website hosting is generally managed by dedicated servers, whereas routers focus on directing traffic between devices rather than hosting content.

C (Extends the cable range and allows connections to be made by increasing the signal strength) YOUR ANSWER

This description pertains more to devices like repeaters or range extenders, which amplify signals to extend the range of a network. Routers do not inherently extend cable range; rather, they manage data routing across networks.

D (Converts incoming analog data into digital and outgoing digital data into analog) YOUR ANSWER

This function is characteristic of modems, which facilitate the conversion between analog and digital signals for internet connectivity. Routers do not perform this function; they operate at a higher level by directing data packets within a network rather than converting signal types.

Conclusion

A router's primary role is to manage network traffic efficiently by keeping a comprehensive table of known devices, which enables it to route data packets accurately. While other devices serve specific functions like hosting or signal conversion, the router's unique responsibility of traffic management is essential for maintaining effective communication within a network.
