Wi-Fi is a trademarked name of the Wi-Fi Alliance but it is commonly used to refer to any wireless Internet connection or hotspot. Each of the three major operating systems (Windows, Apple and Linux) supports wireless Internet access and as of 2010, most laptops come equipped with wireless capabilities.

Once enabled, free Wi-Fi is simply an unprotected wireless network connection or hotspot that you can access. Writer Bio
