what is wifi is it wireless internet?

Answer 1

Technically wi-fi doesn't stand for anything. It just sounds like hi-fi, so wi-fi. It's basically a replacement for wired LAN: go wireless. It's still a LAN, with local access points and so on. By itself, it has nothing to do with the Internet at all. You can only go as far as you can receive your access point's signal. No signal, no network.

HOWEVER, most modern sources of wi-fi signals are from "wireless routers", which is a wireless access point built into a broadband router and a 4-port switch. Thus, a wireless router connected to a broadband access such as cable Internet or DSL Internet, will give you a "local" wireless internet, so a LOT of people confuse wi-fi with wireless Internet, and looks like you're one of them.

Answer 2

Short for ‘wireless fidelity’. A term for certain types of wireless local area networks (WLAN) that use specifications conforming to IEEE 802.11b. WiFi has gained acceptance in many environments as an alternative to a wired LAN. Many airports, hotels, and other services offer public access to WiFi networks so people can log onto the Internet and receive emails on the move. These locations are known as hotspots.
