Summary

Description
English: Usage of a computer in layers:
  1. software running in user mode (green)
  2. software running in kernel mode (red)
  3. hardware (blue)
  4. human (user, sand)
This ordering of the 4 layers is strictly the correct one: the Human-machine interface is between the Human and the Hardware!
Deutsch: Nutzung eines Rechners in Ebenen:
  1. Software in user mode (grün)
  2. Software in kernel mode (rot)
  3. Hardware (blau)
  4. Mensch (Benutzer, sandfarben)
Diese Anordnung der 4 Ebenen ist streng genommen korrekt: der Nutzer interagiert durchaus mit den (User-Mode) Programmen, in dieser Interaktion besteht ja der Zweck der Nutzung; und die Benutzungs-Schnittstellen dieser Programme müssen ergonomisch sein! Allerdings befindet sich Mensch-Maschine-Schnittstelle zwischen Mensch und Hardare (den Ein- und Ausgabegeräten, nicht dem Prozessor natürlich). Sämtliche Eingabesignale werden von den Gerätetreibern verarbeitet, welche i.d.R. teils des Kernels sind. Der Kernel gibt seinerseits die Eingabesignale weiter an die Usermode-Programme. Die Ausgabe verläuft ebenso: Usermode-Programme senden Anfragen an den Kernel (sie dürfen und können die Hardware nicht selbst ansprechen!) dieser verarbeitet diese und reicht sie ultimativ an die Gerätetreiber für die Ausgabegeräte weiter.
Magyar: Ez a 4 szint elrendezése szigorúan helyes: a ember-gép felület az ember és a hardver között van! A felhasználó mindig a legfelső szinttel lép kapcsolatba velük, az összes program egyszerre fut.
Română: Aranjarea celor 4 niveluri poate fi înșelătoare: nivelul uman este în partea superioară a nivelului software, deoarece, pe de o parte, utilizatorul folosește în mod natural programele care rulează în prezent pe computer; cu toate acestea, desigur, interacționează doar cu hardware-ul.
עברית: סידור ארבעת הרמות יכול להטעות: הרמה האנושית נמצאת בראש מעל רמת התוכנה מכיוון שמצד אחד המשתמש משתמש באופן טבעי בתוכנות הפועלות כיום על המחשב; עם זאת, כמובן, זה מתקשר רק עם החומרה
