Course abstract

The aim of the study course is to prepare IT specialists for the implementation, maintenance and integration of Linux server operating systems in an organization's computer network.
In the lectures of the study course, students continue to acquire knowledge about the creation of computer network infrastructure using servers with the Linux operating system. In the laboratory, students acquire skills and competencies in the installation, implementation, management and maintenance of Linux servers.
The course is intended to be implemented as full-time classes, which include lectures, laboratory work and independent work.

Learning outcomes and their assessment

After completing the course student will have:
•knowledge of Microsoft Windows Server and GNU / Linux servers operating systems history of the development, deployment, management and maintenance;
•skills of creation, infrastructure management and maintenance of computer network using both Microsoft Windows Server and GNU/Linux operating systems;
•competence in working in groups or individually, using information acquiring, preparation and processing tools, presentation preparation and informative materials about computer networks’ operating systems Microsoft Windows Server and Linux development, as well as in assuring others and proving their own opinion.

Requirements for awarding credit points

Attendance at lectures should be above 75%, if absences are above 25%, then a report on non-attended lecture topics should be prepared.
All laboratory works and independent work must be developed and credited, for each laboratory work and independent work in the e-learning environment of LLU a work task and a description of the evaluation criteria of the results to be achieved are placed.
Must have passed the theory tests.
You must pass the exam.

Description of the organization and tasks of students’ independent work

The student must independently prepare for the tests of the theory tests, acquire literature and Internet resources on the topics covered in the lectures.
The student must independently prepare for laboratory work using assignments and video recordings in the e-learning environment.
As part of the independent work, the student must create a Linux server on Microsoft Azure or another cloud computing platform.

Criteria for Evaluating Learning Outcomes

The tests of the tests are evaluated with a mark in the 10-point system, a successful mark of the test can be obtained if at least 40% of the test questions are answered correctly, by repeatedly rewriting the failed tests, the test is reduced by 1 point.
Laboratory works and independent work are assessed with a test without a mark, but for each laboratory work developed and passed in time, the student gets 0.1 points at the exam grade.
The exam task consists of:
1. test on the theoretical material acquired in the study course;
2. practical task on the topics acquired in the laboratory work of the study course.
If all tests are successfully written by the beginning of the individual study and examination period, then the student may not pass the theoretical test of the exam and equate the arithmetic mean of the marks with the marks of the theoretical test.
The examination mark is calculated as the arithmetic mean of the theory test (or the arithmetic mean of the second part of the study course test) and the practical task of the examination, to which points for laboratory work are added.
