Device driver

More commonly known as a driver, a device driver or hardware driver is a group of files that enable one or more hardware devices to communicate with the computer's operating system. Without drivers, the computer would not be able to send and receive data correctly to hardware devices, such as a printer.

What devices need drivers?

Hardware devices that are unknown by the operating system or that have features that are unknown by the operating system all require drivers. Below is a list of hardware devices and peripherals that require drivers.

Card reader

Controller

What devices may not need drivers

Today's operating systems have a lot of generic drivers that allow hardware to work at a basic level without needing drivers or software. However, if that device has features unknown to the operating system, it will not work without drivers. For example, you could plug any keyboard into a computer and expect it to work. However, if that keyboard has any special buttons or features, they will not work until the drivers are installed.

CPU

Disc drive

Fan

Hard drive

Heat sink

Joystick

Keyboard

Mouse

Monitor

Power supply

RAM

Speakers

Thumb drive

UPS

Note

The operating systems generic driver may not be updated as often as the drivers from a hardware manufacturer or computer manufacturer.

What happens if a driver is not installed?

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 releases a driver update to fix the

problems.
