Understanding Bluetooth

Bluetooth is the name of a short-range wireless network technology that is designed to let devices connect to each other without need for cables or a Wi-Fi network access point. The two main uses for Bluetooth are to connect peripheral devices such as keyboards or mice to a computer and to connect hand-held devices such as phones and PDAs (Personal Digital Assistants) to computers. Here are just a few of the many uses of Bluetooth:

• Wirelessly connecting a keyboard and mouse to a computer so that you don't have to fuss with cables. This is marginally useful for desktop computers because it eliminates the need for cables. But it is even more useful for laptop computers, because it lets you use a keyboard and mouse simply by placing them next to the laptop.
• Synchronizing the address book in your cell phone with your computer's address book, with no cables.
• Exchanging files between your Pocket PC or Palm PDA and your laptop or desktop computers.
• Using a cord-free headset with your cell phone.
• Connecting a Global Positioning System (GPS) device to a computer so that it can track your location. This is especially useful when used in your car with a laptop, Pocket PC, or Palm PDA.
• Swapping electronic business cards between handheld computers.
