For example, suppose you need to write a tool that has access to core operating system data structures, which can be accessed only by code running in kernel mode. http://jcibook.net/device-driver/define-device-drivers.html

A driver communicates with the device through the computer bus or communications subsystem to which the hardware connects. have a peek here Please help improve this article by adding citations to reliable sources.

In such cases, it is important that the hardware manufacturer provides information on how the device communicates. Device Controller This is true for a device that connects directly to the Peripheral Component Interconnect (PCI) bus. The main reason for writing a software driver is to gain access to protected data that is available only in kernel mode.

A device driver acts as a translator between the hardware device and the programs or operating systems that use it.

The component that runs in user mode is called an application, and the component that runs in kernel mode is called a software driver. Read More » The 7 Layers of the OSI Model The Open System Interconnection (OSI) model defines a networking framework to implement protocols in seven layers. After the driver gets the data from the device, it returns the data to the operating system, which returns it to the application. Understand the principles of data residency IT administrators should assess data residency on a case by case basis.

The application calls a function implemented by the operating system, and the operating system calls a function implemented by the driver. Please consider expanding the lead to provide an accessible overview of all important aspects of the article. These factors make it more difficult and dangerous to diagnose problems.[3] The task of writing drivers thus usually falls to software engineers or computer engineers who work for hardware-development companies. Some examples of devices that need drivers are hard drives, DVD drives, and PCI cards.

In Linux environments, programmers can build device drivers as parts of the kernel, separately as loadable modules, or as user-mode drivers (for certain types of devices where kernel interfaces exist, such SourceForge. 2010.
