  3. Tradition for egenudviklet software UNIX?

  4. 1982 AT&T UNIX System III Ingen multi-CPU-support $$$$$ Dyr kildetekst Dokumentation ikke tilgængelig

  5. 1979 UNIX version 7 1975 UNIX version 6

  6. Unirex Supermax Operating System SMOS Vi kan skrive pænere systemkald end UNIX har UNIX’ systemkald bliver en skal uden om vore egne Vi vil ikke være begrænset af hvad UNIX kan Der var visse ting i UNIX vi misforstod

  7. Pænere systemkald creat(name, mode) char*name; creat_un(ioud, uname, prot, mode, size, errblock) short int *ioud; char *uname; short intprot, mode; intsize; char *errblock; HANDLE WINAPI CreateFile( _In_ LPCTSTR lpFileName, _In_  DWORD dwDesiredAccess, _In_ DWORD dwShareMode, _In_opt_  LPSECURITY_ATTRIBUTES lpSecurityAttributes, _In_      DWORD dwCreationDisposition, _In_      DWORD dwFlagsAndAttributes, _In_opt_  HANDLE hTemplateFile);

  8. Opfindelser In-memoryprocesses (Multithreading) Memorypartitions (Sharedmemory) Messagesemaphores (Messagequeues) Redirection files (Symbolic links) User file process (Virtual file system)

  9. Misforståelser Proces 1 (init) Proces 117 Proces 87 Proces 118 Proces 119

  10. Misforståelser Main process 121 Main process 28 Main process 53 Produce Proces 117 Proces 120 Proces 87 Gemmate Spawn Proces 118 Proces 119

  11. Memory Memory Memory Memory MCU MCU SIOC DIOC Virtual Terminal interface Ét sæt kommandoer Specificeret i »Terminology« Ét sæt tastetryk

  12. ASCII ISO 664 / DS 2089 ISO 8859-1 / Latin 1 if (i<0 øøarrÆiÅ> 8) æ printf("FintØn"); å Poul Schl>ter
