Bluetooth is a standard for wireless connection of computers and other electronic devices that are within close proximity of each other.
Modern versions of the Windows operating system come with Bluetooth support, but before you can use it, you’ll also need to have a device that supports Bluetooth as well.
Bluetooth comes with different versions, and each version comes with different features. You may need to know what Bluetooth version your computer is running so you know what features you can expect to find available when you connect your devices.
The key feature for the Bluetooth 4.0 for example, according to the executive director of the Bluetooth SIG, is the low-energy technology.
