An Internet router is a device that connects multiple devices to the internet and allows them to communicate with each other. It acts as a traffic director, managing data packets between your home network and the wider internet. Routers can be wired or wireless, providing flexibility in how devices connect. In addition to connecting devices, routers often include features like firewalls for security and network management tools. They can support various protocols, such as Wi-Fi, enabling smartphones, laptops, and smart home devices to access the internet seamlessly.
