MS-DOS est un\u00a0syst\u00e8me d’exploitation\u00a0pour\u00a0ordinateurs\u00a0personnels \u00e0 licence propri\u00e9taire d\u00e9velopp\u00e9 par Microsoft au d\u00e9but des ann\u00e9es 1980. Il a \u00e9t\u00e9 utilis\u00e9 tout d’abord sur le premier ordinateur grand public : l’IBM\u00a0PC. Il dispose par d\u00e9faut d’une interface en ligne de commande, il est mono-t\u00e2che et mono-utilisateur.\u00a0<\/strong><\/p>\n\n\n\n

MS-DOS a \u00e9t\u00e9 l’OS le plus r\u00e9pandu sur\u00a0PC\u00a0pendant la premi\u00e8re d\u00e9cennie de l’informatique ouverte au grand public. Il est rest\u00e9 une sous-couche des syst\u00e8mes d’exploitation Windows jusqu’\u00e0 l’arriv\u00e9e de\u00a0Windows XP\u00a0qui a amorc\u00e9 le passage au syst\u00e8me NT. Dans Windows 95 et 98 par exemple, l’interface graphique \u00e9tait automatiquement charg\u00e9e au d\u00e9marrage de l’ordinateur, mais on pouvait acc\u00e9der \u00e0 MS-DOS pour ex\u00e9cuter des programmes en\u00a0ligne de commande.\u00a0<\/p>\n\n\n\n

Le syst\u00e8me d\u2019exploitation le plus r\u00e9pandu des 20 premi\u00e8res ann\u00e9es de l\u2019informatique grand public<\/h2>\n\n\n\n

La premi\u00e8re version de MS-DOS a \u00e9t\u00e9 r\u00e9v\u00e9l\u00e9e en 1981, \u00e0 l’occasion de l’inauguration du\u00a0premier IBM PC. En correspondance avec les configurations mat\u00e9rielles de l’\u00e9poque, elle \u00e9tait compatible avec des\u00a0disquettes\u00a05\u20331\/4 de 160 ko limit\u00e9es \u00e0 64 fichiers, car les r\u00e9pertoires n’\u00e9taient pas support\u00e9s. Au cours des ann\u00e9es 1980, de nombreuses mises \u00e0 jour ont \u00e9t\u00e9 publi\u00e9es pour suivre le d\u00e9veloppement de l’informatique. Microsoft a peu \u00e0 peu ajout\u00e9 le support des\u00a0disques durs\u00a0au format FAT12, puis FAT16, une interface graphique (le Shell), la prise en charge des\u00a0disquettes\u00a03,5\u2033 et le support de\u00a0partitions\u00a0de plus en plus grandes.<\/p>\n\n\n\n

\u00c0 partir des ann\u00e9es 90, Microsoft enrichit MS-DOS d’outils comme ScanDisk (v\u00e9rification du syst\u00e8me de fichiers), DriveSpace (logiciel de compression) et Scanreg (d\u00e9pannage du registre). Les derni\u00e8res versions de MS-DOS (7.1 et 8) ajoutent le support du syst\u00e8me de fichiers FAT32.<\/p>\n\n\n\n

La derni\u00e8re version stable de MS-DOS date de septembre 2000. Son support s’est arr\u00eat\u00e9 \u00e0 la fin de l’ann\u00e9e 2001, vingt ans apr\u00e8s sa pr\u00e9sentation initiale. Les versions modernes de Windows offrent\u00a0un invite\u00a0de commande\u00a0dont les fonctions proviennent de MS-DOS. Il permet d’ex\u00e9cuter des programmes en mode texte et int\u00e8gre un \u00e9mulateur reprenant le fonctionnement de MS-DOS 8.<\/p>\n\n\n\n
