| | 44 | 1. Un thread de processus informatique représente une exécution de ce processus. Il est défini par une pile d'exécution pour ses fonctions, un état des registres du processeurs et des propriétés comme un état d'exécution (RUNNING, READY, DEAD, et d'autres que nous verront plus tard). Combien de threads a-t-on par processus au minimum et au maximum ? |

| | 50 | 1. Tous les threads d'un processus se partagent le même espace d'adressage, et donc le même code, les mêmes variables globales, les mêmes variables dynamique (nous les verrons dans un prochain cours). Est-ce qu'ils se partagent les piles aussi ? |
