WiFi vs. Wireless
Mia Lopez 
What is the difference between WiFi and Wireless (as in the 802.11g that is available on my laptop wireless card)?

Wi-Fi (pronounced /ˈwaɪfaɪ/) is a trademark of the Wi-Fi Alliance for certified products based on the IEEE 802.11 standards. This certification warrants interoperability between different wireless devices.
In some countries (and in this article) the term Wi-Fi[1][2] is often used by the public as a synonym for IEEE 802.11-wireless LAN (WLAN).
Not every IEEE 802.11 compliant device is certified by the Wi-Fi Alliance, which may be because of certification costs that must be paid for each certified device type. The lack of the Wi-Fi logo does not imply that a device is incompatible to certified Wi-Fi-devices.
Wi-Fi is used by most personal computer operating systems, many video game consoles, laptops, smartphones, printers, and other peripherals.

WiFi generally refers to wireless LAN (local area network) -- the kind you get when you set up an 802.11a/b/g/n router.
Wireless usually means a wireless connection provided by a cell phone company, used by smartphones and laptops with a wireless Internet card.
(I'm located in the U.S. People may use these terms differently in other countries.)
3WiFi is the "consumer" term - it was coined to rhyme with Hi-Fi, something that the average computer user is familiar with, so that the technology doesn't appear threatening or too "techy".
7"Wireless" is generic and can include BlueTooth, cellular data, and even mice and keyboards that dont connect to the PC using a cable. WiFi is a trademarked certification. That is, "Wireless" includes (is a superset of) "WiFi".
In the Germany, it's common use to say WLAN or Wireless (LAN). So the wording is not WiFi but Wireless.
In my opinion, there's no difference between these words in a non technical environment.
