If a PC does not already have Bluetooth, it can be added with a USB dongle. Bluetooth dongles are generally about the size of traditional USB flash drives and are available in most electronics stores.
Installing a Bluetooth dongle is a matter of plugging the device into a PC and installing the necessary software and drivers. The software is often found on an accompanying CD that can be installed on most computers regardless of the operating system. Once the Bluetooth dongle is installed, it can be synced with external devices such as phones and headsets to enable wireless data transfer and communications.
