Answer: D - A router moves frames of data between two nodes by using IP Addresses.

Key Takeaway - Of the devices listed here, Routers operate at the highest level of the network, routing data from a source to a destination through the use of IP Addresses. As a result, Routers can ensure delivery of data beyond the local network. Switches and some Bridge move data through the use of MAC addresses. Although every device has a MAC address, it is too difficult a method to use outside the local network-so Switches ensure delivery within a Local Area Network. Hubs broadcast data to every connected node and therefore do not use any addressing or routing system.
