Everywhere you go, you’re likely to hear the term “WiFi.” Maybe it’s the restaurant that claims to have free WiFi or a friend who asks for the WiFi password. You use WiFi all the time, but there’s a good chance that you don’t really know what it is or how it works.

Some people might tell you that WiFi is just another term for the Internet, but that’s not exactly true.

WiFi and Internet are NOT the same thing

Although WiFi is typically used to access the Internet on portable devices like smartphones, tablets, or laptops, in actuality, WiFi itself is only used to CONNECT your devices to a router. The router, in turn, provides Internet access.

So, WiFi is the WIRELESS CONNECTION to your devices, NOT the Internet itself. Instead of using
a wire, WiFi uses radio waves to transmit information.

Advantages of using WiFi:

• WiFi makes it possible for devices to connect to the Internet wherever they can locate a WiFi signal.
• And because you do not have to use a cable, you’re not limited to a specific area in your house/office to be able to use the Internet.
• WiFi is expandable. Bought another tablet? No problem. Simply enable WiFi in its settings, and it's good to go.
• WiFi can also wirelessly give you access to other devices, such as printers and help you wirelessly transfer files from one computer to another.
