Wifi and Bluetooth

The difference between Wifi and Bluetooth,,,

Wi-Fi and Bluetooth are two different types of wireless technology that are used in devices such as laptops, mobile phones, printers and video game hardware. While Bluetooth and Wi-Fi both facilitate wireless communication between devices, the practical uses differ. Wi-Fi allows computers, video game consoles and smartphones to connect to a local area network (LAN), and Bluetooth enables connections between individual devices, such as mobile phones and headsets.

Wifi:

Wi-Fi technology enables local area network and Internet connections. With Wi-Fi, a laptop or desktop computer can connect to a home or professional network's wireless modem. This modem will bridge a connection with a router or hub that serves as a gateway to the Internet. Using Wi-Fi, you can use your computer to browse the web without wires or cables, which you would otherwise need. Many mobile phones such as the iPhone are also equipped with Wi-Fi capability.

Bluetooth:

Unlike Wi-Fi, Bluetooth does not connect devices to local area networks or the Internet; rather, it connects two devices together. With Bluetooth, you can connect your computer, phone and other electronics to hardware peripherals such as headphones, headsets, printers, keyboards or a computer mouse. Using Bluetooth, you can connect your headphones to your MP3 player or your keyboard to your computer without a need for wires. Usually Bluetooth peripherals are powered by batteries that need to be charged or replaced.
