An internet router is a device that connects multiple devices to the internet and allows them to communicate with each other. It directs data traffic between your home network and the wider internet, ensuring that information reaches the correct destination. 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 also support various protocols, enabling different types of devices, such as smartphones, computers, and smart home devices, to work together seamlessly on the same network.
