Demonstration of the Syllabus Coherence with the Curricular Unit's Objectives:
In this curricular unit the fundamental concepts of computer network organization are presented in the introductory chapter; physical and data link layers of the OSI model are presented in the two following chapters and, in the last chapter, local area networks are studied. The learning objectives are achieved by supplementing the theoretical concepts with real use cases deployed in lab environment using simulators and network equipment.
Teaching Methodologies (Including Evaluation):
The transmission of knowledge in this syllabus will be with theoretical oriented lectures and practical classes in laboratory environment. The lectures present the fundamental concepts for understanding the items of the program. In practical classes students solve exercises eventually using physical or virtual equipment (in the context of simulators) where suitable. The final grade is calculated according to the following formula:
practical grade = 0,8 * (project) + 0,2 * worksheets
theoretical grade = (theoretical Test 1 + theoretical Test 2) / 2
final Grade = (2 * theoretical grade + Practical grade) / 3
Both the Practical and Theoretical grade have to be positive (> = 9.5).
If any of the components is not positive the curricular unit will not be completed and the positive component will be preserved according to the regulations.
Demonstration of the Coherence between the Teaching Methodologies and the Learning Outcomes:
Learning objectives focus on understanding how computer networks are structured according to layered models. In this curricular unit students will learn about the Network’s physical and logical link layers, as well as, local area networks (LANs). The resolution of practical exercises and projects, involving conceptual design, but also configuration, implementation, testing and management of enterprise local area networks allows students to acquire the necessary skills.
