Inorder to make it easy to share data
Posted: 07-11-2012 @ 22:17:39
it is a wireless technology to share data with devices located around 10 metres range of the source device.

Bluetooth is a mode of connectivity which can be used to pair devices of similar companies using a bluetooth router and thus share two devices in terms of connectivity to the internet, access files, folders, share photos and even add contacts to the phone. The recent developments include share by touch of Nokia...... awesome technology

Bluetooth is a short-range wireless technology used for connecting and transferring information between devices such as mobile phones, laptops, PCs, PDAs, printers, digital cameras, mice and keyboards. Bluetooth makes it easy to connect two devices wirelessly when it would be otherwise impossible to connect them with cables. In the wireless world, Bluetooth is a snail: home Wi-Fi networks and wireless hotspots are almost 20 times faster. With the latest incarnation of Bluetooth (version 2.0), devices must be within about 15 metres of each other to connect, and achieve data transfer speeds up to 2 or 3Mbps (megabits per second) — real world experiences are usually half of this. Expect an average-length song to transfer from a Bluetooth-capable laptop to a phone with Bluetooth in a minute; pictures or ring tones take about 10 seconds. If you have Bluetooth on your phone but not on your PC, you can pick up a Bluetooth USB adaptor or "dongle", for under AU$30.

It's a wireless technology to sent data between 2 mobile.its purly unexpencieve and time saver also very simply to use.

Bluetooth is a proprietary open wireless technology standard for exchanging data over short distances (using short wavelength radio transmissions in the ISM band from 2400-2480 MHz) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security. Created by telecoms vendor Ericsson in 1994,[1] it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization. Bluetooth is managed by the Bluetooth Special Interest Group, which has more than 15,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics.[2] The SIG oversees the development of the specification, manages the qualification program, and protects the trademarks.[3] To be marketed as a Bluetooth device, it must be qualified to standards defined by the SIG. A network of patents is required to implement the technology[citation needed] and are only licensed to those qualifying devices; thus the protocol, whilst open, may be regarded as proprietary.

asked. But still, if you want to know then let me tell you that bluetooth is one of the most easiest ways to transfer multimedia objects from on device to another.

Bluetooth is a standard wire-replacement communications protocol primarily designed for low power consumption, with a short range (power-class-dependent, but effective ranges vary in practice; see table below) based on low-cost transceiver microchips in each device. Because the devices use a radio (broadcast) communications system, they do not have to be in visual line of sight of each other, however a quasi optical wireless path must be viable. The effective range varies due to propagation conditions, material coverage, production sample variations, antenna configurations and battery conditions. In most cases the effective range of Class 2 devices is extended if they connect to a Class 1 transceiver, compared to a pure Class 2 network. This is accomplished by the higher sensitivity and transmission power of Class 1 devices. While the Bluetooth Core Specification does mandate minimums for range, the range of the technology is application specific and is not limited. Manufacturers may tune their implementations to the range needed for individual use cases. To use Bluetooth wireless technology, a device has to be able to interpret certain Bluetooth profiles, which are definitions of possible applications and specify general behaviors that Bluetooth enabled devices use to communicate with other Bluetooth devices. These profiles include settings to parametrize and to control the communication from start. Adherence to profiles saves the time for transmitting the parameters anew before the bi-directional link becomes effective. There are a wide range of Bluetooth profiles that describe many different types of applications or use cases for devices.

Come on buddy, Why are you asking such foolish questions? Mostly everyone in this world knows what is bluetooth. Anyways, coming to the point of answering your question, bluetooth is a service in mobiles and laptops which is used to transfer files and data from 1 bluetooth enabled device to another bluetooth enabled device. I think this is the easiest definition that you can understand what is bluetooth, because all the other answers on this question are high tech answers and are all just copy paste from the internet.
