Which device typically connects a local network to the internet?

The device that typically connects a local network to the internet is a router. Routers are specifically designed to route data between different networks, enabling devices within a local area network (LAN) to communicate with external networks, including the internet. When a device within the LAN, such as a computer or smartphone, wants to access online resources, it sends that request to the router, which then forwards the request to the internet service provider (ISP). The router also receives data from the internet and directs it back to the appropriate device within the local network.

In addition to connecting to the internet, routers also handle various networking functions, such as providing IP addresses to devices within the network (through DHCP), enabling Network Address Translation (NAT) for security and efficient IP management, and sometimes providing firewall protection to safeguard the local network from external threats. This capability makes routers essential for home and enterprise networks alike, as they facilitate not only connectivity but also management and security of data traffic.

Other devices mentioned, such as hubs, switches, and access points, serve different purposes within a local network. Hubs are simple devices that connect multiple devices in a LAN without directing data intelligently. Switches are more advanced than hubs, as they can manage data traffic efficiently by directing
