An Internet router is a device that connects multiple devices, like computers and smartphones, to the internet. It acts as a traffic director, ensuring that data flows smoothly between your devices and the internet. When you send a request, like opening a website, the router helps find the best path for that information to travel. Routers can be wired or wireless. A wired router uses cables to connect devices, while a wireless router allows devices to connect without physical cables, using Wi-Fi. Many modern routers also come with built-in security features to protect your network from unauthorized access.
