WiFi is a popular term that is used referring to wireless communications between computers and other computer related devices. Regular radio waves are used to broadcast and receive just like a pair of walkie talkies, but with much higher frequency.
Now days you will find many areas around town that offer free WiFi internet access, but the most common use for WiFi is in the home. If you have high speed Internet (Satellite, Cable, DSL etc. ) and a piece of equipment that is called a wireless router, then you have WiFi.
In the illustration above you can see what equipment is used in a typical home WiFi network. In some cases, the Internet service provider will supply a wireless router/modem combination when you subscribe to their service.
The main benefit of WiFi is Wireless internet connection. Many electronic devices have WiFi built-in and can access the internet anywhere within range of wireless router. This means that you can browse the internet from your couch when using a WiFi laptop computer. If you own a WiFi Internet Radio you can listen to over 14,000 stations in your kitchen, bedroom , or bathroom. Most cell phones have WiFi internet access also.
An electronic device cannot communicate with a WiFi router unless it has a WiFi receiver/transmitter (also called a WiFi card or module) built-in. Most laptops have a built-in WiFi card which can communicate with nearby wireless routers. you can purchase a USB WiFi Antenna if your computer does not have built-in WiFi. Modern USB WiFi antennas can be connected to almost any Windows computer to improve or enable WiFi communication.
WiFi works using two-way communication between devices.There are several different types of WiFi (such as 802.11a, 802.11b,802.11g,802.11n), but the end result is still the same with wireless communication. In the technical world WiFi is translated to 802.11, which is a group of standards created by the Electronics Engineers (IEEE) and Institute of Electrical.
