The practical purpose of Wi-Fi is to provide wireless connectivity to digital content. This content may include audio and visual material, Internet, or other data that can be transmitted among several users. Wi-Fi makes transferring information easier, as it eliminates the need for cables. Even HP colour Laserjet cartridges are now being used in the latest HP wireless printers that actually connect to the internet and allow you to print right from their touch screen panel.

Generally, Wi-Fi is used to connect to the Internet wirelessly. A Wi-Fi enabled device such as a laptop, game console, PDA or mobile phone can connect to the Internet through Wi-Fi when in range of a wireless network that is connected to the Internet.

Hotspots are a major selling point for hotels around the world and most coffee shops now advertise “Wi-Fi Hotspot” on their front window to attract customers. But customers be aware, a hotspot doesn’t mean free Internet, some establishments charge to use their Internet while others are free of charge, so shop around and make sure you get yours for free, after all, you are paying six bucks for a cup of coffee, the least they can do is let you check your Facebook for free!
