Class Data Communication and Newtorks

This corse aims at providing the basic concepts related to data communication networks, from its basic usage to planning, design and management of computer networks, both in resources and security roles, allowing a better understanding of the emerging potentials.

Information and communication are two of the most important strategic areas for business success. Currently almost any medium to large-sized company in areas from banks and insurance companies to entertainment and health has an IT department where network and data communication professionals have a fundamental role.

Theory lectures supported in slides and practical assignments explored in labs.

In line with the goal of increasing the students' autonomy some contact hours turned into individual study hours. For this reason, there will be an increased student supervision.

The evaluation has a both a practical and a theory component.

There theory component will be based on two written tests, each weighting 50%.

The practical component will be graded based on labs and assignments and will weight 50% to the final mark.

Both will require a minimum score of 10.

Final Mark = (Theory Component + Practical Component) / 2

Students will also have the opportunity to attend the exams in the dates contemplated in the regulations.

The final approval will be given according to the Regulamento das Unidades Curriculares com Forte Componente Laboratorial, of FE.

Should there be any doubts concerning any of the evaluation marks, the teacher may conduct an oral evaluation in order to confirm the results.
