A router is a device that directs information between different networks, like a traffic cop deciding which cars should go where. In most homes, a router connects all your family's devices (computers, phones, tablets) to the internet. When you click on a website, your request travels through the router, which sends it out to the internet and then routes the response back to your specific device.

Think of it this way: your house might have five people all using the internet at once, each doing something different. The router keeps track of who requested what and makes sure the right information gets to the right person.

Routers often look like small boxes with antennas, usually tucked away near where internet service enters your home. Many routers today are wireless, meaning devices connect to them through invisible radio signals called Wi-Fi rather than physical cables.

In woodworking, a router is a completely different tool: a powerful handheld machine that hollows out grooves in wood or shapes its edges, used by carpenters to make decorative designs or create joints where pieces fit together.
