Wi Fi stands for Wireless Fidelity (Wi-Fi) and can be defined as a system where like an Ethernet or LAN connection, laptops can connect to the internet. Wi Fi offers you the opportunity to link to a network anywhere within a specific area or "hot spot" where a connection is available. It is all wireless, and fun to use. The only dissadvantage is that once you move out of the area where the network coverage is, you no longer have the Wi-Fi or network connection.

It is expected that WI-FI will become an extremely popular in the next couple of years. It is expected to become as common as electrical outlets and phones in the future, and will add huge levels of convenience as well as increased productivity for laptop owners. Immagine going to the airport, and having to connect to the internet you can just walk into a Wi-Fi zone and go on straight away. Hotels, Coffeeshops and businesses all around the world could be equiped with Wi-Fi connections soon.
