What is a Router?

Before we delve into the world of routers, you need to understand what a broadband connection is and how it works. According to Dictionary.com, broadband is "a high-speed, high-capacity transmission medium that can carry signals from multiple independent network carriers. This is done on a single coaxial or fiber-optic cable by establishing different bandwidth channels. Broadband technology can support a wide range of frequencies. It is used to transmit data, voice and video over long distances simultaneously."

Routers take information that arrives through your broadband signal via a modem, decipher it, and deliver it to your computer. The router will also choose the best route for the data packet so that you receive the information quickly.
