What is Wi-Fi?

In the interest of accuracy, the following are excerpts from the website “How Stuff Works”. I recommend it highly.

A wireless network uses radio waves, just like cell phones, televisions and radios do. In fact, communication across a wireless network is a lot like two-way radio communication. Here's what happens:A computer's wireless adapter translates data into a radio signal and transmits it using an antenna.A wireless router receives the signal and decodes it. The router sends the information to the Internet using a physical, wired Ethernet connection.The process also works in reverse, with the router receiving information from the Internet, translating it into a radio signal and sending it to the computer's wireless adapter.

Being able to connect to the Internet in public “hotspots” is extremely convenient. Wireless home networks are convenient as well. As long as they all have wireless adapters, several devices can use one router to connect to the Internet. A wireless router allows you to use wireless signals or Ethernet cables to connect your computers to one another, to a printer and to the Internet. Most routers provide coverage for about 100 feet (30.5 meters) in all directions, although walls and doors can block the signal.. This connection is convenient, virtually invisible and fairly reliable; however, if the router fails or if too many people try to use high-bandwidth applications at the same time, users can experience interference or lose their connections._ from the website How Stuff WorksNow that most computers and new printers have wireless built in, many people have their own WI-Fi network, also known as a LAN, or Local Area Network. IF you don’t have proper encoding protection to keep it to yourself, your close neighbors can “piggy-back” and use it too.
