A person with a Wi-Fi enabled device such as a computer, cell phone or PDA can connect to the Internet when in proximity of an access point. The region covered by one or several access points is called a hotspot. Hotspots can range from a single room to many square miles of overlapping hotspots. Wi-Fi can also be used to create a mesh network. Both architectures are used in community networks.
Wi-Fi also allows connectivity in peer-to-peer (wireless ad-hoc network) mode, which enables devices to connect directly with each other. This connectivity mode is useful in consumer electronics and gaming applications.
When the technology was first commercialized there were many problems because consumers could not be sure that products from different vendors would work together. The Wi-Fi Alliance began as a community to solve this issue so as to address the needs of the end user and allow the technology to mature. The Alliance created the branding Wi-Fi CERTIFIED to show consumers that products are interoperable with other products displaying the same branding.

Wifi stands for wirelesss fidelity, wireless connects to hotspots which connect to the internet, you can have a total wire free network which connects to each other and the internet, its awesome files & webpages in the air? yes, it travels in the air which is intercepted by your wifi card on your laptop or desktop and its lightening fast too.
Its a hardware, some come with softwares to show you connections spots around public spaces as you need a connection hotspot to connect to the internet, you do not need a software except its drivers.
Wifi in short:
PC with WIFI CARD- NO WIRES-CONNECTS TO INTERNET!
