What is the interface between device driver and operating system?

The Device Controller works like an interface between a device and a device driver. I/O units (Keyboard, mouse, printer, etc.) typically consist of a mechanical component and an electronic component where electronic component is called the device controller.

Whats is the relationship between kernel and drives?

In general, drivers provide detail implementation to specific physical or logical devices, while kernel then provide a set of interface for drivers, and manage them in a higher abstracted level (HAL). By the way, kernel does a lot more than managing hardware resources.

What do device drivers use to communicate with the kernel?

Generally a driver communicates with the device through the computer bus which is used to connect the device with the computer. Device drivers works within the kernel layer of the operating system. Each driver contains the device specific codes required to carry out the actions on the device.

What is device drivers in operating system?

In computing, a device driver is a computer program that operates or controls a particular type of device that is attached to a computer or automaton. A driver communicates with the device through the computer bus or communications subsystem to which the hardware connects.

Which acts as the interface between the operating system and the user?

Answer: The Answer is Operating System.

Which is an interface between operating system kernel and end user?

Kernel is a part of operating system. Operating system acts as an interface between user and hardware. Kernel acts as an interface between applications and hardware.

What is kernel in an operating system what is the difference between OS and kernel?

Difference between Operating System and Kernel:

Operating System	Kernel
Operating System is a system software.	Kernel is system software which is part of operating system.
It also provides protection and security.	It’s main purpose is memory management, disk management, process management and task management.

What is difference between kernel and device drivers?

Answer: In general, drivers provide detail implementation to specific physical or logical devices, while kernel then provide a set of interface for drivers, and manage them in a higher abstracted level (HAL). By the way, kernel does a lot more than managing hardware resources.

What is the use of device drivers?

The main purpose of device drivers is to provide abstraction by acting as a translator between a hardware device and the applications or operating systems that use it. Programmers can write higher-level application code independently of whatever specific hardware the end-user is using.
