Honestly, I can't believe how many people do not know what WiFi means. I was sitting in a cafe and this group of yuppies entered arguing loudly about the Dallas game they saw on TV. One was bragging he saw the game on his
new Panasonic HDTV when a guy piped in and said he saw the game in the internet through WiFi. They all try to look like they understand, you know nodding and mumbling. But I distinctly heard and saw one guy nudge and ask his friend what WiFi is. I mean, almost all people know WiFi, even kids in middle school. But hey, no use griping about it. So out of the goodness of my heart, let me fill you in about WiFi.
WiFi is a contraction of the term
Wireless Fidelity. Generally, it refers to all types of 802.11 network (dual-band, 802.11a, 802.11b, etc.). The WiFi Alliance popularized the term to lessen confusion with LAN networks. In addition, products tested and approved as WiFi-capable are inter-operable with each other regardless of their manufacturer or brand. This means that in a media center (a network of WiFi-capable electronics with DVD, TV, and computer) it doesn't matter if your TV is Sony and you're a Mac user. The TV can still be used to Net surf, the same way that the Mac can be used to watch a TV game or show. All this flexibility is possible with minimum effort and no unsightly wires (wireless, duh).
