What does a router do?

Rationale

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

Routers are essential networking devices that facilitate communication between different networks by directing data packets efficiently. They maintain a routing table to keep track of known devices and their locations, enabling optimal data transmission paths.

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

While routers do facilitate data routing, they do not typically provide web hosting services. Web hosting is usually the function of a server, whereas routers primarily focus on directing traffic and managing network connections without hosting websites themselves.

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

This function is characteristic of a modem, not a router. Modems are responsible for converting data formats for transmission over various types of networks, while routers handle the distribution of these data packets within and between networks.

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

This description better fits the function of a network extender or repeater, which amplifies signals to extend network coverage. Routers do not inherently increase signal strength; instead, they manage the flow of data across networks.

Conclusion

The primary function of a router is to manage network traffic by keeping track of known devices and their connections through a routing table. This capability is crucial for ensuring efficient data packet delivery across networks. Options A, B, and C describe functions associated with other devices, emphasizing the unique role routers play in network management and communication.
