Kernel
 
[dt. Kern] der, der zentrale Teil eines Betriebssystems, in dem alle »lebenswichtigen« Funktionen zusammengefasst sind. Der Kernel genießt besonderen Schutz und kann normalerweise nur von dazu berechtigten Personen (unter Unix vom Systemadministrator) modifiziert werden. Während die meisten Systeme wie Windows, MacOS oder Solaris einen jeweils einheitlichen Kernel besitzen, gibt es bei Unix und Linux unterschiedliche und z. T. inkompatible Kernels. Beispiele für Unix-Kernels sind Mach, der GNU-Kernel Hurd (GNU) und der Linux-Kernel (Linux). Eine Weiterentwicklung des Kernel-Konzepts ist die Errichtung eines sog. Mikrokernels, gewissermaßen ein »Kern im Kern«.
