DOS yokusebenza: inkcazelo kunye namathuba

Umhla wokuzalwa DOS yokusebenza libe nokuthathelwa ingqalelo njengoko 1980, xa uphuhliso yokuqala, ethwele igama QDOS yadalwa. Le nkqubo isetyenziswa ngokubanzi ifumene ngo-1987 kwaye isetyenziswa kwada kwanamhla.

inkqubo yokuyisebenzisa DOS: iimpawu ngokubanzi

System (OS) nekhompyutha yi-software zithwele kwi computer siqu. It uphumeza incoko nomntu yenza ulawulo PC kunye nezibonelelo zayo, umenzi iinkqubo ezahlukeneyo. Ngenxa kwindlela yokusebenza kunye umsebenzisi izicelo Sinokukhawuleza ukunxibelelana izixhobo PC (interface).

Undoqo lwale nkqubo iifayile MSDOS MSDOS.SYS kunye I0.SYS ukuba zilayishwe ibe imemori yi umlayishi kwaye awayesoloko apho. Ifayile lokuqala lisebenzisa iinkonzo ezisisiseko-kwinqanaba eliphezulu MSDOS, kwaye enye Incedisa inkqubo isiseko kwimveliso igalelo.

umsebenzisi Ukwenziwa input imiyalelo ezenziwe nge kumqhubekekisi umyalelo, nto leyo iqaphelwa ifayile COMMAND.SOM agcinwe kwi diski kunye engundoqo. Eminye imiyalelo e DOS, ezifana DIR, TYPE, nabanye wenziwe iprosesa umyalelo. Zibizwa ngokuba imiyalelo zangaphakathi. Eminye imiyalelo yangaphandle yenziwa ngoncedo iifayile bangaphandle esele zilayishwe kwi kwinkumbulo kwaye sisebenze nge COMMAND.SOM. Emva kokuba Ekupheleni kwale nkqubo kumqhubekekisi lisusa inkqubo engawajonganga, kunye neengxelo sokulungiselela ukuphunyezwa ngakumbi izenzo lomsebenzisi.

imiyalelo bangaphandle ukuba isebenzise DOS operating system kusiwa njengoko izifayile ezisecaleni kunye nenkqubo. Iveza izenzo uphawu inkonzo ezahlukeneyo (khangela kwidiski, ifomathi, njl ..).

Udibaniso ku MSDOS inkqubo kwigalelo neziphumo abaqhubi isixhobo ezibonelela ukusetyenziswa non-umgangatho izixhobo ezikhoyo okanye inkonzo entsha. Ezi nkqubo zilayishwe kungena kukhunjulwa PC nenkqubo, yaye amagama abo abhalwe ngendlela CONFIG.SYS ekhethekileyo yoqwalaselo lwefayile. Oku kwenza kube lula ukuba ukongeza izixhobo ezintsha ngaphandle kokusebenzisa iifayile MSDOS nkqubo.

DOS inkqubo yokusebenza: nemisebenzi esisiseko

Uxanduva engundoqo nokugcinwa kwenkqubo (indalo, ukugcinwa, susa) ifayile, ezo ezifana naluphi na olunye, kwaye isethi iindawo memory ezithile data. Xa iifayile zithengiswe zilayishwe kungena engundoqo kukhunjulwa ikhompyutha, kwaye phantsi kolawulo kwenkqubo (OS).

ifayile nganye kufuneka ukuba ibe entsonkothileyo yaye elula igama. igama nzima imelwe igama lefayile kunye nokwandiswa. Ngokungafaniyo nezinye iinkqubo zenqanaba eliphezulu (Windows), i-MS-DOS Igama lefayile inokuba akukho ngaphezu abalinganiswa ezisibhozo. Ulwandiso lwefayile ibonisa uhlobo okanye ukuba iprogram ethile, efana ifayile yeenkcukacha okanye itekisi.

Kakade ke, xa kuthelekiswa ne-windose MS DOS - yinto ujongano eyahlukileyo ngokupheleleyo. Ukuba inkqubo yokuqala, zonke izixhobo eziyimfuneko yonke inkcazelo ngokwegrafu kwi computer, umsebenzi kwinkqubo DOS kuyantsonkotha kwaye ifuna izakhono ezizodwa kunye nolwazi imiyalelo.

Njengoko i-interface phantsi kwenkqubo DOS phambi kokuba umsebenzisi ubonakala a screen emnyama kunye umyalelo-umgca kuphela. Kwaye, umzekelo, ukukhuphela inkqubo okanye umdlalo (ezixhaswa yi system) kuya kufuneka ukuba ufake imiyalelo embalwa.

Emva kokuba ukubonakala inkqubo Norton Commander ukusebenza kwinkqubo MS-DOS kuye kwaba lula kakhulu. Kwakhona, DOS inkqubo yokusebenza lisebenza njenge inkqubo-tasking, kwaye akavumeli ngokungafaniyo umsebenzi windose kunye neenkqubo ezimbini okanye nangaphezulu ngaxeshanye. Nangona kunjalo, le nkqubo isasetyenziswa, kwaye ikuvumela ukuba ukusombulula imisebenzi eyahlukeneyo ethile. Ukusuka DOS ukuqalisa inkqubo ukubuyisela ulwazi ukukhangela imemori ukujongana nezinye 'nentsimbi' iingxaki.
