Question

Accepted Answer

A router is a computer networking device that links various computer networks together and forwards data between networks by selecting the most appropriate path. Function: routers are intelligent devices that examine the destination address of incoming data and determine the fastest route to send it, acting like a traffic police officer directing data to the right destination. Routers also allow multiple devices to share a single internet connection (for example, connecting a home or school's local network to the internet), and modern routers often include firewalls for added security.
