Routers are essential networking devices that direct data traffic between different networks. They connect multiple devices within a local network (LAN) and manage the flow of data between the LAN and external networks, such as the internet. Routers analyse data packets and determine the best path for them to travel, ensuring efficient and secure data transmission. They often include additional features like firewalls, wireless access points, and network management tools. Routers are vital for both home and office environments, providing reliable internet connectivity and network security.
