WiFi

WiFi: Noun [|Wi-Fi] stands for Wireless Fidelity, and is used to describe Internet and other forms of wireless communication that uses the 2.4, 3.6, and 5 GHz frequency bands. Wi-Fi is also used to describe products that are based on the Institute of Electrical and Electronics Engineers' ([|IEEE]) 802.11 standards. (Source- [|Webopedia.com])

The term //Wi-Fi// is often used by the public as a synonym for wireless Internet (WLAN); but not every wireless Internet product has a Wi-Fi certification. Wi-Fi is supported by most personal computer operating systems, many game consoles, laptops, smartphones, printers, and other peripherals. (Source- [|Wikipedia.org] )

A downside to using WiFi or another wireless Internet connection is a lack of tight security. It is easy to break encryptions on these wireless transmissions and have you or your computer's safety compromised. When using any type of wireless communication with other computers or networks, ensure that you have an updated and efficient firewall, or that you trust the connection source.
