Introduction to Routers

Routers are an important part of a network. They serve as the traffic control for all data as it travels to its destination. When using your computer to surf the Internet, send data, or receive data, one or more routers is usually involved. In this module, you will learn some basic information about routers, how they function, the protocols that control their operation, and the methods that are used to secure them. Throughout this module, you will get a chance to apply your knowledge by working though real-world scenarios.
