Subject specific learning outcomes and competences

Students are acquainted with the basic principles of operating systems (with emphasis on the UNIX operating system) and they understand the influence of operating systems upon the operation of complex computing systems. Students are able to exploit scripts for solving various tasks in a UNIX-based environment.

Learning objectives

The goal is to acquaint students with the principles of operating systems in general and with the basic concepts of the UNIX operating system.
