router

A router is a device that connects different networks, such as your home network and the internet. It directs data traffic between devices like computers, smartphones, and tablets, ensuring information reaches the right destination. Think of it as a traffic controller that manages the flow of digital information, enabling devices to communicate smoothly both within your home and with the wider online world. Routers often provide Wi-Fi, so you can connect wirelessly, and they also add security features to protect your network from unauthorized access.
