Systèmes d'exploitation – Mathématiques et Informatique 5 (MRI)

In computers, operating systems (OS) provide a virtual machine to the user allowing high-level abstractions and an advanced programming and use interface.

The student must know the different levels of a calculator (Hardware, Kernel and Userland) as well as the basic techniques that enable these three levels to function and communicate.

Definition and roles of operating systems, Command interpreters, Process definition, virtual memory allocation, The different modes of process execution, Data flows and redirections, Using system calls, Inter-process communications, File systems (rights management), Scheduling processes, policies. real time, priorities, Multi-core programming (Threads, affinity).

Final review.
