QISMHOI SO MS DOS, DRAYVERHO VA PROGRAMMAHOI REZIDENTI

Qismhoi SO MS DOS. Sistemai operatsionii MS DOS az qismhoi tarkibii zerin iborat ast:

 Sistemai bazavii dokhilkuni-khorijkunii informatsiya (BIOS). In programma dar khotirai doimii kompyuter (ROM –

qead only memoqy) joygir shudaast. Sistemai BIOS amaliyothoi makhsusro ba monandi – sanjishi darajai ba kor omoda budani qismhoi kompyuter (testguzaroni), ba khotirai favrii kompyuter jeg zadani digar qismhoi sistemai MS DOS, ijro namudani amaliyoti universialii dokhilkuni-khorijkunii informatsiya az klaviatura, diskho va ekran ijro menamoyad.

 Ogozkunandai kori DOS. In programmaest, ki dar sektori yakumi diski sistemavi yo vinchester joy doda shudaast. Vazifai asosii in programma – ba khotirai favrii kompyuter

(RAM) jeg zadani faylhoi Io.sys va Msdos.sys meboshad.

  1.  Faylhoi Io.sys va Msdos.sys. In faylho faylhoi asosii sistemavi ba hisob meravand. Dar onho programmahoi asosii sistemai operatsionii MS DOS navishta shudaand, ki onho dar katalogi reshavii diski sistemavi joy doda meshavand.
  2.  Programmai Command.com. In programmaro protsessori komandavi yo ijrokunandai komandahoi istifodabarandai kompyuter menomand.
  3.  Utilithoi sistema. Utilitho programmahoyand, ki onhoro sistemai MS DOS baroi ijro namudani komandahoi beruna istifoda mebarad.
  4.  Drayverhoi qismhoi kompyuter. Drayverho programmahoi makhsusand, ki onho faoliyati in yo on qismi ba kompyuter payvast budaro idora menamoyand. Dar ravandi ba kor omoda gashtani sistemai MS DOS, drayverho ba khotirai favrii kompyuter dokhil karda shuda, to itmomi kori sistema dar on jo boqi memonand. Nomi drayverho dar fayli Config.sys ba qayd girifta meshavand.

Drayverho va programmahoi rezidenti. Drayverho va programmahoi rezidenti imkoniyathoi sistemai MS DOS-ro ziyod menamoyand. Onho korhoero ba subut merasonand, ki sistemai MS DOS onhoro bevosita ijro karda nametavonad.

Drayverho baroi ba sistemai kompyuteri hamroh namudani tajhizoti nav yo baroi ba tavri gayristandarti istifoda burdani tajhizoti mavjuda khizmat merasonand.

Hamin tariq, drayverho programmahoi makhsuse meboshand, ki faoliyati korii in yo on qismi ba kompyuter payvastbudaro tamin va idora menamoyand. Masalan, drayveri Himem.sys imkoniyat medihad, ki sistemai MS DOS khotiraifavrii kompyuterro purratar istifoda barad. Drayveri Keybrd2.sys boshad, imkoniyat medihad, ki az klaviatura harfhoi alifboi rusi dokhil karda shavand.

Baroi ba kor darovardani yagon programma, on hatman ba khotirai favrii kompyuter jeg zada meshavad. Pas az itmomi kori programma boshad, onro sistemai MS DOS az khotirai kompyuter khorij menamoyad. Baze programmaho hamin tavr sokhta shudaand, ki pas az itmomi korashon niz qisman yo purra dar khotira boqi memonand. In namudi programmahoro programmahoi rezidenti menomand. Masalan, qabati programmavii Norton Commanderprogrammai rezidenti ba shumor meravad.

 Savolho:

  1. Sistemai operatsionii MS DOS az chand qism iborat ast?
  2. Funksiyahoi BIOS kadomhoyand?
  3. Drayver gufta chiro mefahmed?
  4. Baroi chi baze programmahoro programmahoi rezidenti meguyand?

 Suporish:

  1. Matni mavzuro bodiqqat khoned va onro naql kuned.
  2. Nomi qismhoi MS DOS va vazifahoyashonro mukhtasar dar daftaraton navised.
