kernel (operating system) wikipedia - EAS
Operating systems communicate with most hardware components using:
- Using a software-simulated interrupt. This method is available on most hardware, and is therefore very common.
- Using a call gate. A call gate is a special address stored by the kernel in a list in kernel memory at a location known to the processor. ...
- Using a special system call instruction. ...
- Using a memory-based queue. ...

https://fr.wikipedia.org/wiki/Noyau_de_système_d'exploitation- Les premiers concepteurs informatiques avaient l’habitude de décrire les différentes couches logicielles d’un système par une analogie : celle du noyau de la noix[2]. En anglais, le mot « kernel » désigne le cerneau, la partie comestible de la noix, c'est-à-dire son cœur[3],[4]. À l'inverse, la coque (partie non comestible de la noix) est une enveloppe très dure qui entoure la p…
