| Summary, etc. | Nous traiterons ici du concept de temps propre au système d’exploitation Unix, en montrant d’une part comment il se distingue de celui de la machine et de l’autre comment il s’articule à la notion d’activité propre à Unix : celle de processus. Nous exposerons ainsi dans un premier temps la temporalité propre aux machines synchrones définies par John von Neumann dans le « First Draft of a Report on the EDVAC » (1945), avant d’analyser dans le détail le code source de la fonction principale et du pilote d’horloge de la version 6 d’Unix (1975). On verra ainsi qu’il peut exister en informatique plusieurs niveaux d’activité et qu’à ces différents niveaux d’activité correspondent autant d’échelles de temporalité. |
| 520 ## - SUMMARY, ETC. | |
| Summary, etc. | This article examines the concept of time in the Unix operating system, and shows how it differs from that of the machine and how it articulates to the notion of activity specific to Unix, i.e. activity as a process. The author first considers the temporality of synchronous machines, as defined by John von Neumann in the “First Draft of a Report on the EDVAC” (1945), before analysing in detail the source code of the main function and of the clock driver of Version 6 of Unix (1975). He thus shows that in informatics several levels of activity can exist, with corresponding time scales. |
