What is the difference between bluetooth and wifi?

Bluetooth is a radio standard primarily designed for low power consumption, with a short range. It is for personal devices like: peripherals such as printers, mice and keyboards; headsets for mobile phones and smartphones; etc. Wi-Fi was intended to be used for mobile devices and LANs, but is now often used for Internet access. It enables a person with a wireless-enabled computer or personal digital assistant (PDA) to connect to the Internet when in proximity of an access point. The geographical region covered by one or several access points is called a hotspot. Hope this helps!
