Question

Which device is used to perform the traffic directing functions on the Internet?

  1. A. Bridge
  2. B. Firewall
  3. C. Router (Correct answer)
  4. D. Hub

Correct Answer

Option C — Router

Detailed Solution & Explanation

A router is a networking device that forwards data packets between computer networks, directing internet traffic. It determines the best path for data to travel from source to destination across multiple networks (including the internet) using routing tables and protocols (such as OSPF, BGP). A bridge connects two similar network segments; a firewall monitors and filters network traffic for security; a hub connects multiple devices in a local network but does not intelligently route data. Routers are the backbone of internet connectivity.
