An interface between two networks. While routers are like bridges, they work differently. Routers provide more functionality than bridges. For example, they can find the best route between any two networks, even if there are several different networks in between. Routers provide network management capabilities such as load balancing, partitioning of the network, use statistics, communication priority, and trouble shooting tools that allow network managers to detect and correct problems even in a complex network of networks. Given these capabilities, routers are often used in building wide area or enterprise wide networks.
