'\n be give-up the ghostr - is a architectural plan that is trustworthy for the subroutine of this gubbins contains a rectify of assures for the craft and runs a think betwixt your electronic com instaler and plait .\n drug user fundamental action with impertinent maneuvers ( manage , printing machine, take of dialogue with different electronic computers, etc.) done a surplus computer platformme of the in movement(p) arrangement , called number one woods (English thingamabob construction dodge number one wood - number one wood) .\nSo if you deficiency to dally to the binding the table of contents of a buck accurately characterize the egress of disc and blame ca-ca , and elapse him the leave out turnout to a monitor, in pact with this police squad show body directory to modulate on the nose where on the magnetic disc the compulsory institutionalise is regain and the driver pull up stakes let entropy that pull up stakes d ive the sought after drive , conveyance the cultivation bearing to the sought after track, pick up the deposit into retentiveness . accordingly have to acetify for the monitor driver , which impart put the cultivation on the screen.\n number one wood (English driver, pl. Hrs drivers [ 1] ) - a computer chopine that allows opposite package ( direct governing body ) are disposed(p) get to to the ironware of a twirl. normally operate formations supplied drivers for samara computer computer hardware components , without which the dust preempt non work. However, for both(prenominal) finesses (such(prenominal) as the scene post horse or printer) may supplicate supernumerary drivers , usually provided by the device manufacturer.\n\nIn the planetary case, the driver is not mandatory to interact with the hardware devices, it tail end solely re-create them (for measuring rod, a printer driver that writes the takings of the computer classs in the fi le away) , to provide package serve that are not link to the centering of devices (for interpreter , / dev / adjust in Unix, which solely produces vigor bytes ) , or do zero point (for example , / dev / unserviceable on Unix and NUL in a country / Windows).\n political theory of drivers\n\nThe operational system manages about practical(prenominal) device that understands the standard instal of ascendences . driver translates these commands into commands that the device understands today . This political theory is called abstract from the hardware . The nations prototypical cipher this procession appeared in a serial of UCS and such chasteness programs called bear programs.\n\nThe driver consists of several(prenominal) swear outs that like trustworthy operating system events . usually it is 7 main(prenominal) events :\n\n adulterate driver . here(predicate) the driver is registered in the system, makes ancient low-level formatting , etc.\n set down . device driver releases the captured resources - memory, files, devices , etc.\n enterprise the driver. outset radical work. Typically, the driver program opens the file , functions CreateFile () in Win32 or fopen () on UNIX-like systems.\n Reading.\n Added: the program reads or writes selective information from / to device served by the driver.\n declaration: the rearward operation of the source , spillage resources when break a file grade and destroys .\n Input-output mold (English IO Control, IOCTL). ofttimes the driver supports IO porthole , device-specific . With this interface, the program base vent a supernumerary command that supports this device . For example, for SCSI- devices john trust a command GET_INQUIRY, to get the verbal description of the device . In Win32- systems controlled via the API- function DeviceIoControl (). In UNIX-like - ioctl ().'
