Class Network Supplements

This Curricular Unit (CU) is presented as a complement to the Computer Networks UC. While the latter covers the network, transport and application layers, this Network Complements UC discusses the fundamentals of communication networks, and the physical and connection layers. Fundamental aspects associated with the design and dimensioning of communications networks are covered, across the most varied transmission media and connection types. Various performance evaluation metrics are also studied, with the aim of gaining quantitative and qualitative sensitivity.

The UC is theoretical and practical. Theoretical classes follow the defined program, presenting theoretical concepts supported by practical examples. In practical classes, exercises are solved on the subject taught. Throughout the semester, weekly exercise sheets will be given on the subject taught. A project, a web application in Python and PHP/HTML, will also be developed throughout the semester. (In addition, Python and PHP/HTML tutorials are provided, with each student building a basic Web application.)
