English

Subject field(s)
  • Molecular Biology

A smaller nucleus located close to and lying partly within a depression on the oral side of the macronucleus.

A micronucleus (MN) is formed during the metaphase/anaphase transition of mitosis (cell division).

Record 2 2002-04-11

English

Subject field(s)
  • Operating Systems (Software)
DEF

The part of an operating system that is specialized for the hardware it is running in.

CONT

The other components of the OS interact with the microkernel in a message-based relationship and do not have to be rewritten when the OS is ported to a new platform. Only the hardware-dependent microkernel has to be reprogrammed.

French

Domaine(s)
  • Systèmes d'exploitation (Logiciels)
DEF

En programmation, partie d'un système d'exploitation strictement dépendante du matériel, et prévue pour être portée depuis un type d'ordinateur vers un autre.

CONT

Il offre une interface indépendante du matériel au reste du système d'exploitation, de sorte que seul le micronoyau doit être réécrit lorsque l'on transfère le système d'exploitation sur une autre plate-forme.
