Entry knowledge

C language programming in Unix environment, computer architecture, Intel x86 assembler, basic principles of operating systems.

Rules for evaluation and completion of the course

During the semester online tests and project. The project must be submitted by the published date, late submission of the project is evaluated 0 points.


Students' knowledge is verified by project elaboration, online tests and a final exam.

Aims

The goal is to acquaint students with the principles and concepts that are used as a basis of modern operating system kernels.

Students are acquainted with the parallel programming using POSIX threads, usage of synchronization primitives, virtual memory and file system.

A deeper understanding of computer systems and system programming.
