Which network component provides a shared connection to the internet for multiple devices?

The correct choice is a router because it is designed to manage and direct data traffic between devices on a local network and the internet. It acts as a gateway that connects multiple devices, such as computers, smartphones, and tablets, to the internet, enabling them to share the same internet connection. The router assigns local IP addresses to each device, allowing for communication within the network while simultaneously facilitating external communication with the internet.

Additionally, routers often come with built-in firewall features, providing a layer of security for the devices connected to the network. They can support both wired and wireless connections, ensuring that various types of devices can access the internet seamlessly.

In contrast, a modem connects directly to the internet and translates signals between your local network and your Internet Service Provider (ISP). It typically handles one device's connection at a time without the capability to manage multiple devices simultaneously like a router does. Similarly, a switch allows multiple wired devices to connect within a local area network (LAN) but does not provide internet connectivity. An access point extends the wireless coverage of a network but requires a router to connect to the internet. Thus, the router is the component that provides a shared connection to the internet for multiple devices.
