Slide 2: 

The term Wi-Fi, first used commercially in August 1999, was coined by a brand-consulting firm called Interbrand Corporation. The term "Wi-Fi" means "Wireless Fidelity". It is a trademark of the Wi-Fi Alliance that manufacturers may use to brand certified products that belong to a class of wireless local area network (WLAN) devices based on the IEEE 802.11 standards. Wi-Fi technology builds on IEEE 802.11 standards.

Slide 3: 

A Wi-Fi enabled device such as a personal computer, video game console, mobile phone, MP3 player or personal digital assistant can connect to the Internet when within range of a wireless network connected to the Internet. Wi-Fi can provide public access at Wi-Fi hotspots provided either free-of-charge or to subscribers to various commercial services. Organizations and businesses - such as those running airports, hotels and restaurants - often provide free-use hotspots to attract or assist clients.

Direct computer-to-computer communications : 

Direct computer-to-computer communications Wi-Fi also allows communications directly from one computer to another without the involvement of an access point. This is called the ad-hoc mode of Wi-Fi transmission.

Advantages :
