Typically, device drivers communicate with a hardware bus or communication subsystem from a hardware-connected device. It sends commands to the device from application software or operating system or receives data from this device.







Why is a device driver required?

Computers and their operating systems are not able to know how to control every device. This is why every device comes with its own driver. The operating system "calls" the driver and the driver "drives" the device.

When a new hardware device is connected to a computer, such as a CD-ROM drive, printer or sound card, it is necessary to install the driver to make it work properly. If the peripheral device changes, its driver must also be changed. The device drivers depending on your operating system are also 8-bit, 16-bit, 32-bit, and 64-bit. New versions of these drivers are written and released by the manufacturer of the device.
