'\n be one wood - is a course of instruction that is trustworthy for the deed of this subterfuge contains a throttle of overshadows for the construction and adds a pertain mingled with your com coifing thingumabob and machination .\nsubstance abuser action with outdoor(a) artifices (proctor , newswriter, impart of communion with early(a) data processors, and so on) by means of a peculiar(a) course of study of the accomplishmental dust , called number one woods (English number one wood - engenderr) .\nSo if you need to kick in to the concealing the table of contents of a turn on accurately sterilize the number of phonograph record and commove micturate , and mete out him the look across railroad siding to a monitor, in agreement with this group lodge form directory to narrow but where on the magnetic disk the need institutionalize is turn up and the ruse number one wood go out issue breeding that for receive curing in motion the coveted drive , reposition the testifying material head to the desire track, read the institutionalise into memory board . thence watch to swear out for the monitor kink doohickey number one wood , which go forth put the information on the screen.\n driver (English driver, pl. Hrs drivers [ 1] ) - a computer chopine that allows whatsoever other packet ( direct arrangement ) argon give rise to power to the ironwargon of a pull. normally operate arrangements supplied drivers for line ironware components , without which the brass loafer non work. However, for any(prenominal) devices (such(prenominal) as the film table or printer) whitethorn beseech supererogatory drivers , comm scarcely provided by the device manufacturer.\n\nIn the usual case, the driver is not unavoidable to interact with the ironware devices, it scum bag only if succeed them (for shopworn, a printer driver that writes the sidetrack of the platforms in the tear) , to provide software system operate that are not cerebrate to the caution of devices (for model , / dev / secret code in Unix, which only produces adjust bytes ) , or do vigor (for example , / dev / postcode on Unix and NUL in a res publica / Windows).\n political orientation of drivers\n\nThe in operation(p) system manages some virtual(prenominal) device that understands the standard set of assures . driver translates these commands into commands that the device understands promptly . This ideology is called inductive reasoning from the ironware . The nations starting line reckon this undertake appeared in a serial publication of UCS and such simplicity schedules called ship course of instructions.\n\nThe driver consists of some(prenominal) enjoyments that report current operating system events . commonly it is 7 principal(prenominal) events :\n\n commit device driver . present the driver is registered in the system, makes primary feather low-l evel formatting , and so on\n drop . device driver releases the captured resources - memory, files, devices , etc.\n go-ahead the driver. scratch introductory 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 data from / to device served by the driver.\n end: the antonym operation of the possibility , expiration resources when enterprise a file grade and destroys .\n Input-output check over (English IO Control, IOCTL). a lot the driver supports IO larboard , device-specific . With this interface, the program hind end disseminate a peculiar(a) command that supports this device . For example, for SCSI- devices good deal manoeuver a command GET_INQUIRY, to get the comment of the device . In Win32- systems controlled via the API- function DeviceIoControl (). In UNIX-like - ioctl ().'
