WIFI: a form of Wireless Local Area Network mostly used in coffee shops, airports, train stations and such so that people don't have to mess around with wires. They are also used in offices so that people can easily access the system.  There are ways to make the network secure, like the WPA (WIFI protected access) which will only allow authorized users through. But most people don't bother with that and anyone can access their network.  WIFI hasn't entirely replaced the standard hard-wired network for two reasons: 1.the CAT5 cable (standared network cable) transmits 5 times faster and is good up to 90 meters 2.there are only a limited amount of channels that can be used at the same time in a WIFI network   Bluetooth could be called a type of radio communication it was created so that devices 10m or so apart could exchange data, even through a wall.

An example of how Bluetooth is used is cell phones. your Bluetooth will show a list of the usernames of the phones nearby, you can send a txt, a photo or a movie to anyone nearby they have to accept it though. Other uses include a "hands off" phone for in the car, you put the Bluetooth earpiece in your ear and you can talk on the phone while driving, it can also be used for a PDA to contact your desktop computer.  Some advantages of Bluetooth are: 1. it can be used over distances 2. It only takes about a thousandth' of a Watt to operate 3. It can reduce the interference of other Bluetooth things operating nearby
