A router is a networking device that is used to route data packets between different computer networks. It is responsible for forwarding data from one network to another, making communication between different devices and networks possible. Option B, limiting access to a network, is incorrect because that is a function of a firewall, not a router. Option C, performing functions like a computer, is incorrect because a router does not have the same capabilities as a computer, such as storing data or running applications. Option D, sorting and delivering email, is incorrect because that is a function of an email server, not a router.
