Answer 1

Wi-Fi is a technology that utilizes electronic equipment to exchange data wirelessly (using radio waves) through a computer network, including high-speed Internet connections. The Wi-Fi Alliance defines Wi-Fi as "any wireless local area network (WLAN) product based on the standards of the Institute of Electrical and Electronics Engineers. However, because most WLANs today are based on these standards, the term" Wi-Fi "is used in general English as a "WLAN" synonym.

A device that can use Wi-Fi (such as personal computers, video game consoles, smartphones, tablets or digital audio players) can be connected to network sources such as the Internet through a wireless network access point. Such an access point (or hotspot) has a range of about 20 meters (65 feet) indoors and wider outdoors. Hotspot coverage can cover an area as large as a room with walls that block radio waves or several square miles - this can be done using several overlapping access points.

"Wi-Fi" is a Wi-Fi Alliance trademark and brand name for products that use a standard family. Only Wi-Fi products that complete the Wi-Fi Alliance interoperability certification trial may use the name and trademark "Wi-Fi CERTIFIED".

Wi-Fi has a changing security history. The first encryption system, WEP, proved to be easily penetrated. Higher quality protocols, WPA and WPA2, are then added. However, an optional feature added in 2007 called Wi-Fi Protected Setup (WPS), has a gap that allows an attacker to get a WPA or WPA2 router password remotely in a few hours. Some companies recommend turning off the WPS feature. The Wi-Fi Alliance has since renewed its testing plan and certification program to ensure all newly certified equipment is immune from harsh AP PIN attacks.
