KI725 (P222-0068, P610-0507) Computer Science and Communication Systems, Master, ASPO 01.04.2016 , semester 1, mandatory course
PIM-SK (P222-0068, P610-0508) Applied Informatics, Master, ASPO 01.10.2011 , semester 3, mandatory course
Workload:
Workload of student for successfully completing the course. Each ECTS credit represents 30 working hours. These are the combined effort of face-to-face time, post-processing the subject of the lecture, exercises and preparation for the exam.

The total workload is distributed on the semester (01.04.-30.09. during the summer term, 01.10.-31.03. during the winter term).
60 class hours (= 45 clock hours) over a 15-week period.
The total student study time is 150 hours (equivalent to 5 ECTS credits).
There are therefore 105 hours available for class preparation and follow-up work and exam preparation.
Recommended prerequisites (modules):
None.
Recommended as prerequisite for:
Module coordinator:
Prof. Dr. Damian Weber
Lecturer:
Prof. Dr. Damian Weber
