This is the course plan for the second semester of the academic year 2023/2024. To check whether the course is being run this semester, go to the Virtual Campus section More UOC / The University / Programmes of study section on Campus. Once teaching starts, you'll be able to find it in the classroom. The course plan may be subject to change.
This course presents the basic concepts of computer networks focusing on Internet and the world wide web (WWW). Moreover, this course deals with multimedia networks as well as the basic principles of security in Internet applications.


This subject trains the student to know the basic concepts and main applications of the Internet network, with special emphasis on the web, as well as basic concepts of Internet security.


Operating systems and Java programming.


Students should have knowledge on operating systems and object-oriented programming (some of the practical assignments are implemented in Java).


The main objective of the subject is that the student knows the basic aspects of internet communications, the protocols of the main applications of information exchange, with special emphasis on the web, and basic aspects of security.

The general objectives are summarized in:

  • To have an overview of computer networks and the Internet.
  • To know the basic functioning of different network applications such as the web, email, name service, etc.
  • To know the basic aspects of web architecture.
  • To know different communication mechanisms for network applications.
  • To know how multimedia applications work.
  • To introduce the principles of security in Internet applications.
The specific skills that the student will work on are:
  • [14] Ability to analyze the architecture and organization of networked computer systems and applications.
  • [15] Know current and emerging communications technologies and know how to apply them appropriately to design and develop solutions based on information systems and technologies.
  • [16] Ability to administer and manage the operating systems and communications of a computer network.


The subject is organized into four units that cover the objectives and competencies presented. They are briefly described next:

Unit 1: Computer networks and the Internet 
This unit presents an overview of computer networks and the Internet. You will see components of all layers of networks always trying not to lose this global vision.

Unit 2: Internet applications
This unit studies the conceptual aspects and implementation of network applications. You can also see the basic functioning of different network applications such as the web, email, name service, etc. Especially you can see the basic aspects of web architecture. Finally, you can see different communication mechanisms for network applications.

Unit 3: Multimedia networks
This unit describes the communication mechanisms and protocols that allow real-time multimedia to work.

Unit 4: Principles of security in Internet applications
This unit presents the basic security aspects to keep in mind when running network applications

 The study guide that can be found in the virtual classroom details contents that will be worked on.

The assessment process is based on students' own work and the assumption that this work is original and has been carried out by them.

In assessment activities, the following irregular behaviours, among others, may have serious academic and disciplinary consequences: someone else being involved in carrying out the student's assessment test or activity, or the work being not entirely original; copying another's work or committing plagiarism; attempting to cheat to obtain better academic results; collaborating in, covering up or encouraging copying; or using unauthorized material, software or devices during assessment.

If students are caught engaging in any of these irregular behaviours, they may receive a fail mark (D/0) for the assessable activities set out in the course plan (including the final tests) or in the final mark for the course. This could be because they have used unauthorized materials, software or devices (e.g. social networking sites or internet search engines) during the tests, because they have copied text fragments from an external source (internet, notes, books, articles, other student's projects or activities, etc.) without correctly citing the source, or because they have engaged in any other irregular conduct.

In accordance with the UOC's academic regulations , irregular conduct during assessment, besides leading to a failing mark for the course, may be grounds for disciplinary proceedings and, where appropriate, the corresponding punishment, as established in the UOC's coexistence regulations.

In its assessment process, the UOC reserves the right to:

  • Ask the student to provide proof of their identity, as established in the university's academic regulations.
  • Request that students provide evidence of the authorship of their work, throughout the assessment process, both in continuous and final assessment, by means of an oral test or by whatever other synchronous or asynchronous means the UOC specifies. These means will check students' knowledge and competencies to verify authorship of their work, and under no circumstances will they constitute a second assessment. If it is not possible to guarantee the student's authorship, they will receive a D grade in the case of continuous assessment or a Fail in the case of final assessment.

    For this purpose, the UOC may require that students use a microphone, webcam or other devices during the assessment process, in which case it will be the student's responsibility to check that such devices are working correctly.


You can only pass the course if you participate in and pass the continuous assessment. Your final mark for the course will be the mark you received in the continuous assessment.
