What is the function of a router in a computer network?

Correct answer: To provide Internet access to multiple devices by routing traffic between the local network and the Internet.

Explanation:

• A router forwards data packets between different networks (for example, between your home network and the Internet).

• To allow multiple devices to use one Internet connection, routers commonly use Network Address Translation (NAT) and provide DHCP to assign local IP addresses.

• Routers may also include basic security features (firewall rules, access control), but comprehensive network security is usually handled by dedicated security systems.

• Other functions mentioned in the options are handled by different components: displaying web pages is done by web browsers or servers, and wireless connectivity is provided by a wireless access point (though many routers combine routing and Wi‑Fi in one device).
