DOS ezisebenza uhlelo: incazelo kanye amathuba

Usuku lokuzalwa kohlelo ezisebenza DOS kubhekwe njengento 1980, lapho ukuthuthukiswa yokuqala, onegama QDOS yadalwa. Indlela esetshenziswa kabanzi uhlelo lithole ngo-1987 futhi wasebenzisa kuze kube manje.

uhlelo Operating DOS: izici jikelele

System (OS) kwe-computer kuyinto isofthiwe ukulayishwa kwikhompyutha siqu. It lucwaningo inkhulumomphendvulwano umuntu kwenza PC ukuphathwa nemithombo yawo, engikhiphela izinhlelo ezihlukahlukene. Ngenxa indlela yokusebenza kanye umsebenzisi izicelo sizikhandle ukuxhumana namadivayisi PC (esibonakalayo).

Umnyombo uhlelo amafayela MSDOS MSDOS.SYS futhi I0.SYS ukuthi abasindwayo ku inkumbulo ngumuntu Loader futhi njalo samanje lapho. Ifayela lokuqala nokobana a ephezulu ezingeni izidingonqangi MSDOS, kanti omunye ongumphelelisi ohlelweni base okukhipha input.

imiyalo Icubungula umsebenzisi okokufaka wenza nge processor umyalo, okuyinto ezalethwa ifayela COMMAND.SOM ligcinwa disk kanye core. Ezinye imiyalo DOS, ezifana DIR, TYPE, nabanye owenziwa processor umyalo. Zibizwa ngokuthi imiyalo yangaphakathi. Okunye imiyalo zangaphandle abazenzi ngosizo amafayela yangaphandle ukuthi abasindwayo ku inkumbulo futhi ugijime njengoba ngokusebenzisa COMMAND.SOM. Ngemva kwesimiso wokugaya okususiwe uhlelo ngekhanda, futhi imibiko ezilungele ukuqaliswa eminye yezenzo yomsebenzisi.

imiyalo angaphandle engikhiphela uhlelo lokusebenza DOS ithunyelwa njenge amafayela ehlukile ohlelweni. Bakha izenzo inkonzo uhlamvu ezahlukene (hlola disk, ufometha, njll ..).

Ngaphezu MSDOS okokufaka okukhipha uhlelo kukhona abashayeli kudivayisi ezinikeza ukusetshenziswa okungezona ezijwayelekile amadivayisi ekhona noma isevisi entsha. Amahlelo la asiwa alayishwe inkumbulo PC nge uhlelo, futhi amagama abo abhalwe ngendlela ifayela ukumisa CONFIG.SYS ekhethekile. Lokhu kwenza kube lula engeza amadivayisi amasha ngaphandle kokusebenzisa amafayela uhlelo MSDOS.

uhlelo DOS ezisebenza: imisebenzi eyisisekelo

Isibopho eyinhloko nokugcinwa kohlelo (ukudalwa, isitoreji, susa) amafayela, okuyinto azifane yimuphi omunye, futhi iqoqo othize inkumbulo izindawo idatha. Lapho ekucubunguleni amafayela alayishwe main inkumbulo computer, futhi ingaphansi nokulawula uhlelo (OS).

ifayela ngalinye kumele libe negama ezingase zibe yinkimbinkimbi futhi elula. igama Complicated imelelwa igama lefayela isandiso. Ngokungafani nezinye izinhlelo ezingeni eliphakeme (i-Windows), igama lefayela MS-DOS ungaba izinhlamvu ezingaphansi kwezingu-ayisishiyagalombili. Ukwelulwa ifayela kubonisa uhlobo noma okuqondene uhlelo oluthile, njenge-ifayela idatha noma umbhalo.

Yiqiniso, uma kuqhathaniswa nabangu-windose MS DOS - it is a esibonakalayo ehluke ngokuphelele. Uma uhlelo lokuqala, wonke amathuluzi adingekayo kanye nalo lonke ulwazi uvezwa imidwebo kuyi-computer, umsebenzi DOS uhlelo kuba yinkimbinkimbi futhi kudinga amakhono akhethekile ulwazi imiyalo.

Njengoba interface ngaphansi DOS uhlelo ngaphambi umsebenzisi ibonakala screen black nge womyalelo kuphela. Futhi, isibonelo, ukulanda uhlelo noma umdlalo (kusekelwa uhlelo) kuyodingeka ufake imiyalo ambalwa.

Ngemva ukubukeka Uhlelo Norton Commander ukusebenza MS-DOS uhlelo ke sekulula kakhulu. Futhi, uhlelo lokusebenza DOS uba uhlelo olulodwa-tasking, futhi ayikuvumeli ngokungafani umsebenzi windose nge izinhlelo ezimbili noma ngaphezulu ngesikhathi esisodwa. Nokho, lesi simiso lisasebenza, futhi ikuvumela ukuba ukuxazulula imisebenzi ehlukahlukene ethize. Kusukela DOS uhlelo ukubuyisela ulwazi ukuhlola imemori futhi ukubhekana nezinye 'nensimbi' zezinkinga.
