Question 11

Connects to a local area network and serves as a gateway to the internet

A router is a device that connects to a local area network (LAN) and facilitates access to the internet, acting as a gateway for devices within that network to communicate with external networks.

A) Monitors traffic on the network and blocks it if it triggers safety rules

This option describes the function of a firewall rather than a router. While some routers come with integrated security features, their primary role is not to block traffic but to manage data traffic between networks.

B) Extends the cable range and flows connections to be made by increasing the signal strength

This choice refers to the functionality of a signal booster or repeater, which is different from a router. A router does not merely extend cable range; it manages data traffic and connects networks to the internet.

C) Provides services, such as website hosting and routing, for various devices

While routers do facilitate routing for various devices, they do not typically host websites. This option conflates the roles of routers and web servers, making it an inaccurate description of a router's primary function.

D) Connects to a local area network and serves as a gateway to the internet

This option accurately describes the fundamental role of a router. It connects multiple devices within a local area network and allows them to access the internet, serving as a critical gateway for data transmission.

Conclusion

The correct answer, D, accurately captures the primary function of a router as a device that links a local area network with the internet. Options A, B, and C incorrectly describe other devices or functionalities, demonstrating a misunderstanding of the router's role in network infrastructure. This distinction is essential for understanding how data is routed and accessed in both local and broader network contexts.
