This subject is taken in the third year, when the student must opt for one of the specialties. Anyway, this subject is compulsory for all students. Due to the importance that computer networks - especially the Internet - have nowadays, it is considered that all students should acquire basic knowledge about this area.

In this subject, the basic requirements for developing applications in which the network plays a key role are studied. Besides, the most relevant network applications are also studied. The subject focuses on the part of application development that is linked to the existence of the Internet, giving special importance to the study of developments in TCP/IP. Models for the creation of network applications and interfaces for their development are studied.

1 Network application design

2 Network application development

3 Network applications

4 Network application's security

5 Advanced tools for the development of network applications.

Being basically a practical subject, in the theoretical classes the main concepts are explained and the student then goes into greater depth following the references provided by the professor. Theoretical concepts are put into practice in the practical classes.



Students have to carry out two types of practical work in groups. 1) They do the practical work proposed in the laboratory classes, always supported by the professor. This practical component uses to be short (one session) and highly directed, without much margin for moving away from the objective.

2) Students have to carry out (mainly out of classroom) other more general practical work, using the main concepts taught in class in a wider and more realistic way. The goal of the practical work is to design a network application and the nature of the designed application must be agreed with the professor beforehand.

• Continuous Assessment System
• Final Assessment System
• Tools and qualification percentages:
  • Percentages and evaluation methods are detailed in the following sections. (%): 100

Students have to choose between two types of evaluation: continuous or overall. Initially, any student attending to classes is considered as enrolled in continuous evaluation, so attending to classes is a necessary condition in continuous evaluation.

Continuous evaluation is divided into three parts. In the first part, the students do a practical work in groups, mainly outside class hours, consisting on the design of a network application design. This represents 15% of the mark. Secondly, in the last theme the practical work done in the laboratory is evaluated. It represents 5% in the final mark. Finally, the remaining contents, both theoretical and practical, are evaluated by 3 written exams. The student whose average mark of the first two exams is less than 3 will go to overall evaluation.

The students that don’t meet the conditions to remain in continuous evaluation will automatically go to overall evaluation. The ones that do meet the conditions will definitively be evaluated in continuous evaluation unless otherwise requested through eGela within the period indicated by the teacher. In any case, at least 60% will be evaluated at the end of this period. In continuous evaluation waiving the call is not possible, so students aiming to waive the call must go to global evaluation as explained before.

In the case of overall evaluation, the student has to take a written exam that represents 100% of the final mark. To waive the call it is enough not to take the exam.

In this case the student must be evaluated by the overall evaluation. Its conditions are those described for the ordinary call.
