Explain the role of device drivers

Ans 1 a) Device driver is a component in operating system which is used to interact with the hardware device through a communication sub system to which the hardware connects. Ans 1b) when any new device is installed in the system add a device wizard View the full answer.  · A device driver is a particular form of software application that is designed to enable interaction with hardware devices. Without the required device driver, the corresponding hardware device fails to work. A device driver usually communicates with the hardware by means of the communications subsystem or computer bus to which the hardware is Estimated Reading Time: 2 mins. Device Drivers are the set of subroutines that interact with the hardware, means the Kernel interacts with I/O devices by means of device driver. Device Drivers are included in the kernel and consist of data structure and functions that control one or more devices, such as hard disk, keyboard, mouse,monitors etc.

Device drivers control the interaction between the operating system and the device that they are controlling. For example, the file system makes use of a general block device interface when writing blocks to an IDE disk. The driver takes care of the details and makes device-specific things happen. User-mode Device Driver – Other than the devices which are brought by kernel for working of the system the user also bring some devices for use during the using of a system that devices needs device drivers to functions those drivers falls under User mode device driver. For example user needs any plug and play action that comes under this. A device driver usually communicates with the hardware by means of the communications subsystem or computer bus to which the hardware is connected. Device drivers are operating system-specific and hardware-dependent. A device driver acts as a translator between the hardware device and the programs or operating systems that use it.

18 ສ.ຫ. A driver is a software component that lets the operating system and a device communicate with each other. Purpose of Device Drivers Device drivers are necessary to permit a computer to interface and interact with specific devices. They define the messages and. 29 ຕ.ລ. A driver communicates with the device through the computer bus or communications subsystem to which the hardware connects. What is device driver.
