How does a router work?

A wireless router is used to connect a computer, or network, to another computer or network. It works either through a broadband cable or a DSL (Digital Subscriber Line) internet connection. It uses radio waves to broadcast signals, and also to collect them. The wireless router's main function is to decipher the radio waves and translate them into terms that we can understand. It helps us to relay information from one place to another, or multiple places.
