Public Data Services (SPD)

The main objective of this subject is for students to complete their training in computer networks. Particular emphasis is placed on the services and networks offered by public telecommunications operators to meet new demands (in terms of public Internet, private virtual networks, etc.), and those offered for conventional services (telephone service, dedicated lines, etc.).

Knowledges

1. Students will learn the characteristics of telecommunication equipment, networks, and services used for transmitting data both across very large areas and in metropolitan areas.
2. Students will be familiarised with the technology, protocols, specific terminology, and international recommendations concerning the most important fields of public telecommunications.

Abilities

1. Cognitive low level abilities related with backbone and access data networks.
2. Interpersonal and collaborative abilities.

Competences

1. Competences related with cognitive and comprehensive levels, and with the application of concepts.
2. Traversal competences related with collaborative work and autonomic learning.

Theory sessions (6 credits) rounded off with application sessions involving problem-solving exercises(1.5 credits). Use of ATENEA as the integration tool to facilitate the cooperative learning.

The academic activities that students will have to carry out during the course and that will be subject of their grading are the following: 1) lectures attendance, 2) participation in the course activities, 3) composition of a technical report done in groups (of two or three students), which will be publicly presented at the end of the course, and 4) two tests that will be distributed along the course. There will be also a final exam that will be a way for the students to increase their mark, or to get recovered to those who fail in the continuous evaluation.
The performance of the students in the above-mentioned activities will be accounted to obtain the students final grade. This accounting will be done according the following proportion:
1.  Na: Attendance to class, 10%. A minimum of 75 % class attendance is required.
2.  Ntlls: Course activities that will be carried out along the course, 20%.
3.  Ncrts: Average grade of the two tests that will be carried out during the course, 50%.
4.  Ntr: Realization and presentation of the work in groups, 20%. In the realization of this activity, besides the quality of the work, the capacity of abstraction and synthesis, the collaborative degree of the members of the group will also considered. The grade will be given individually depending on the grade obtained by the group, the clarity of the public presentation, and the opinion of the members of the group on the others members contribution to the whole.
Thus, the final grade of the subject (Nf) for students who have done the continuous evaluation will be obtained from the following formula:  
Nf = Na x 0,1 + Ntlls x 0,2 + (Max. [Ncrts/Nef]) x 0,5 + Ntr x 0,2
Those students that would not want to follow the continuous assessment procedure will have to state this circumstance at the very beginning of the course. And then, they will have the option of only being evaluated by the final exam. The grade of these students will be what they will obtain in the final exam (Nef).
