WHAT IS A WIFI ROUTER?
A router is simply an intelligent device that understands where data comes from and routes it to the intended destination. For example, let’s say you want to access a web site on the internet. After you enter the url in your browser, data is sent along your network to your router. Your router talks to other routers, electronically, to determine where the web site actually is. It then send your request to that location. A WiFi router is a specialized type of router that can also understand data transmitted though the airwaves. Typically, a router have many other features associated with it, such as a firewall and DHCP services. If your computer is connected to a router, the router will supply an address to your computer through it’s DHCP function. If you have a single internet connection, a router is also used to connect to that connection and will allow anywhere from 100 to 250 other computers to share that single internet connection.
