A modem can also function as what other piece of hardware?

A) A hub
B) A switch
C) A router
D) A network interface card

A modem can also function as a router, as it is capable of routing data between the internet and devices on the local network. A modem typically has a built-in router, but it may also have a separate router connected to it. While a modem and router serve different functions, they are often combined into a single device. A modem is not typically used as a hub, switch, or network interface card.
