A device driver is a computer program allowing higher-level computer programs to interact with a device. A driver typically communicates with the device through the computer bus or communications subsystem to which the hardware is connected. When a calling program invokes a routine in the driver, the driver issues commands to the device. Once the device sends data back to the driver, the driver may invoke routines in the original calling program. Drivers are hardware-dependent and operating-system-specific. They usually provide the interrupt handling required for any necessary asynchronous time-dependent hardware interface.
Writing a device driver requires an in-depth understanding of how the hardware and the software work for a given platform function. Because drivers require low-level access to hardware functions in order to operate, drivers typically operate in a highly privileged environment and can cause system operational issues if something goes wrong. In contrast, most user-level software on modern operating systems can be stopped without greatly affecting the rest of the system. Even drivers executing in user mode can crash a system if the device is erroneously programmed. These factors make it more difficult and dangerous to diagnose problems.
Generally end user do not understand the importance of drivers but they realize the same when they don’t get a flawless or smooth performance system. Most of the issues occur due to low quality or buggy drivers. When it comes to windows devices driver development, there is a huge cry in the industry for the good developers and debuggers, because it needs in-depth understanding of how the hardware and the software interacts in the given platform to function, operating system internal knowledge, expertise in programming, hardware architecture knowledge, exposure in debugging tools etc. So the industry pays very handsome salary for the debugger, Tester and developer for development of windows device Driver.
