More commonly known as a driver, a device driver or hardware driver is a group of software files that enable one or more hardware devices to communicate with the computer’s operating system. Without drivers, a hardware device such as a computer printer would not be able to work with the computer, which is why every hardware device in and connected to your computer has associated drivers.
If the appropriate driver is not installed, the device may not function properly if at all. For Microsoft Windows users, a driver conflict or an error can be seen in the Device Manager. If problems or conflicts are encountered with a driver, the computer manufacturer or hardware manufacturer will release a driver updates to fix the problems.
