A personal computer that does not have embedded Bluetooth can use a Bluetooth adapter that enables the PC to communicate with Bluetooth devices. While some desktop computers and most recent laptops come with a built-in Bluetooth radio, others require an external adapter, typically in the form of a small USB " dongle ".
In the context of an operating system, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. [1] A driver provides a software interface to hardware devices, enabling operating systems and other computer programs to access hardware functions without needing to ...
The Bluetooth protocol stack is split in two parts: a "controller stack" containing the timing critical radio interface, and a "host stack" dealing with high level data. The controller stack is generally implemented in a low cost silicon device containing the Bluetooth radio and a microprocessor.
In PC to peripheral usage models (such as dial up networking using a cellular phone), the PC may need to download device drivers or other software for that peripheral from a web site. To do this the driver must know the proper identity of the peripheral.
A wireless network interface controller may be implemented as an expansion card and connected using PCI bus or PCIe bus, or connected via USB, PC Card, ExpressCard, Mini PCIe or M.2. The low cost and ubiquity of the Wi-Fi standard means that many newer mobile computers have a wireless network interface built into the motherboard.
A driver in software provides a programming interface to control and manage specific lower-level interfaces that are often linked to a specific type of hardware, or other low-level service. In the case of hardware, the specific subclass of drivers controlling physical or virtual hardware devices are known as device drivers.
