A wired router is a device that connects multiple computers and other devices to a network using physical cables. It allows these devices to communicate with each other and access the internet through a single connection. Wired routers typically use Ethernet cables for fast and reliable data transfer, making them ideal for environments where speed and stability are essential. In addition to connecting devices, wired routers often include features like built-in firewalls and network management tools. They can support various network protocols, ensuring compatibility with different devices. Overall, wired routers are a fundamental component of many home and office networks, providing secure and efficient connectivity.
