Guest lecture / keynote speech Theory lectures, as well as illustrative examples and problems of the subject.
Mixed objective/subjective test The content of the lectures will be evaluated through two exams, one in the middle of the term and the other on the official date of the final exam.
ICT practicals Explanation and monitoring of ICT practices on the subject contents. The OMNET++ INET simulator and a network emulation tool based on virtualization will be used.

Assessment
Methodologies Competencies Description Qualification
ICT practicals B1 B3 C3 It will be evaluated by means of the work reports on the practices carried out by the student. The due dates of the different work reports will be spaced throughout the term. 50
Mixed objective/subjective test A17 A55 B1 B3 C6 The content of the guest lecture / keynote speech methodology will be evaluated through two exams, one in the middle of the term and the other on the official date of the final exam. 50
 
Assessment comments

Evaluation in the case of part-time students: the same as in the general case. If the student is unable to attend the first mid-term exam, provided that there is a justified reason, an alternative date will be found in agreement with the student.

At the second opportunity, only one final exam will be taken for the guest lecture / keynote speech methodology. The practical grade will be that obtained during the course through the continuous evaluation of the student's work.

The fraudulent performance of the evaluation tests or activities, once verified, will directly imply the grade of '0' in the subject in the corresponding opportunity.
