Bluetooth technology is used for data exchange in between two devices over a short range of distance using wireless technology. It creates a personal area network during the data exchange. This is considered to be a revolutionary technology when it comes to data transferring because it completely avoids the use of data cables. It can also enable connection between more than two devices.

Bluetooth technology was brain child of two scientists Sven and J.Haartsen in 1994 in Sweden.It transfers data from one device to another by converting the data in small packets of information. Hence the protocol is known as Packet based protocol. Bluetooth provides information exchange facility to devices like laptops, faxes, cell phones, fixed line phones, printers, and cameras.

Even during data exchange between two mobile devices, the user still has the option to keep the information secure and private. While the data has to be transferred the user can accept or reject the request whether to allow the other person to grant permission to access his/her data or not.

This technology is most of the time free of cost to access. The user need not pay extra charge for the data transfer that he does.

Few things that users might need to pay attention while using this technology is a drawback called bluejacking. It is usually transferring an image or text message to an ignorant user through this technology. It might include hampering the data in our mobile devices. It might also include transferring viruses into our device. Hence the users were alerted to disable their Bluetooth when not in use or when not required.

Statistics reported that how easy it was for the spread of the Bluetooth worm or virus. And it is also known that the devices use up more battery power when the Bluetooth is enabled all trough out the day. It might also result in slowing down the internet when it used through Bluetooth.

Droid X: What a Beauty

If you don’t like multimedia functions, the Droid X might not be your cup of tea. It has some incredible camera modes (and a really sweet camera to use them with), and also features a really great display. Couple this with the fact that the Droid X can actually function as a wireless hotspot, and you have a very solid multimedia offering that can also be put to great use as a business tool. Of course, even while you say that, you know the main reason you want this phone is because it looks gorgeous and performs its various duties to the same degree of magnificence that one would expect out of a thoroughbred race horse. But whatever the reason, this pretty piece of technology is incredible.

Most of the Droid X is slim and trim, as you would expect from a Droid. But there is one little hump in the back, which gives it character. You notice the hump, but it doesn’t hurt your enjoyment any. This hump allows the 8 megapixel camera to function- it’s not a tiny piece of technology. It also features an HD video camera, which allows it to record incredible videos. There is even a little bonus to the camera’s software, which causes it to recognize and focus in on faces, so you won’t accidentally get a blurry face and a very clear shirt.

The Droid X can function as a wireless hotspot. While all smartphones can get on the Internet on their own, the Droid X is unique in that it can also become a wireless transmitter and receiver for other wireless devices (such as a laptop), and facilitate the Internet for them, as well. This more than makes up for the fact that the Droid does not have its own internal keyboard. Who needs a keyboard on your phone, when you can just get out your laptop and type up whatever it is you want to write?
