What are drivers?

A driver is software that allows the computer to communicate with hardware or devices. Without drivers, the hardware you connect to the computer (for example a video card or a webcam) will not work correctly.

In most cases , the drivers included with Windows, or can be found through the updates offered by Windows Update, which is opened from the Control Panel. If Windows does not have the driver , you can find on the disk supplied with the hardware or device you want, or at the manufacturer’s website.

The driver allows us to interact with a device or a hardware device. A driver typically communicates with the device through the computer bus or communications subsystem to which you connect the hardware.

The driver is usually written by the manufacturer of the hardware device, since it requires a thorough understanding of the hardware to write a working driver.
Sometimes the drivers are written by third parties on the basis of technical documentation issued by the manufacturer, if available.
