What are device drivers?

In computing, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer. Drivers are hardware dependent and operating-system-specific. They usually provide the interrupt handling required for any necessary asynchronous time-dependent hardware interface.

What are the types of device?

Types of Peripheral Devices

There are many different peripheral devices, but they fall into three general categories: Input devices, such as a mouse and a keyboard. Output devices, such as a monitor and a printer. Storage devices, such as a hard drive or flash drive.

How do device drivers work?

A device driver is a piece of software that allows your computer’s operating system to communicate with a hardware device, the driver is written for. When we choose an operation (like Control + P to print a document) on the printer then this command goes to the device driver through the kernel of the operating system.

Why device drivers are required?

Device drivers are required to essentially “teach” an operating system how to communicate with a hardware device. This code allows the operating system to communicate with the hardware in behalf of applications that want to use the device. Some operating systems ship with a number of device drivers already installed.

Where do I find device drivers?
