This is the course plan for the first semester of the academic year 2024/2025. 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.

Description

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.

Professional fields to which it applies

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.

Prior knowledge

Operating systems and Java programming.

Information prior to enrolment

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

Learning objectives and results

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.

Content

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.

Guidelines on assessment at the UOC

Assessment at the UOC is, in general, online, structured around the continuous assessment activities, the final assessment tests and exams, and the programme's final project.

Assessment activities and tests can be written texts and/or video recordings, use random questions, and synchronous or asynchronous oral tests, etc., as decided by each teaching team. The final project marks the end of the learning process and consists of an original and tutored piece of work to demonstrate that students have acquired the competencies worked on during the programme.

To verify students' identity and authorship in the assessment tests, the UOC reserves the right to use identity recognition and plagiarism detection systems. For these purposes, the UOC may make video recordings or use supervision methods or techniques while students carry out any of their academic activities.

The UOC may also require students to use electronic devices (microphones, webcams or other tools) or specific software during assessments. It is the student's responsibility to ensure that these devices work properly.

The assessment process is based on students' individual efforts, and the assumption that the student is the author of the work submitted for academic activities and that this work is original. The UOC's website on academic integrity and plagiarism has more information on this.

Submitting work that is not one's own or not original for assessment tests; copying or plagiarism; impersonation; accepting or obtaining any assignments, whether for compensation or otherwise; collaboration, cover-up or encouragement to copy; and using materials, software or devices not authorized in the course plan or instructions for the activity, including artificial intelligence and machine translation, among others, are examples of misconduct in assessments that may have serious academic and disciplinary consequences.

If students are found to be engaging in any such misconduct, they may receive a Fail (D/0) for the graded activities in the course plan (including final tests) or for the final grade for the course. This could be because they have used unauthorized materials, software or devices (such as artificial intelligence when it is not permitted, social media or internet search engines) during the tests; copied fragments of text from an external source (the internet, notes, books, articles, other students' work or tests, etc.) without the corresponding citation; purchased or sold assignments, or undertaken any other form of misconduct.

Likewise and in accordance with the UOC's academic regulations, misconduct during assessment may also be grounds for disciplinary proceedings and, where appropriate, the corresponding disciplinary measures, as established in the regulations governing the UOC community (Normativa de convivència).

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

Ask students to provide proof of their identity as established in the UOC's academic regulations.
Ask students to prove the authorship of their work throughout the assessment process, in both continuous and final assessments, through a synchronous oral interview, of which a video recording or any other type of recording established by the UOC may be made. These methods seek to ensure verification of the student's identity, and their knowledge and competencies. If it is not possible to ensure the student's authorship, they may receive a D grade in the case of continuous assessment or a Fail grade in the case of the final assessment.

Artificial intelligence in assessments

The UOC understands the value and potential of artificial intelligence (AI) in education, but it also understands the risks involved if it is not used ethically, critically and responsibly. So, in each assessment activity, students will be told which AI tools and resources can be used and under what conditions. In turn, students must agree to follow the guidelines set by the UOC when it comes to completing the assessment activities and citing the tools used. Specifically, they must identify any texts or images generated by AI systems and they must not present them as their own work.

In terms of using AI, or not, to complete an activity, the instructions for assessment activities indicate the restrictions on the use of these tools. Bear in mind that using them inappropriately, such as using them in activities where they are not allowed or not citing them in activities where they are, may be considered misconduct. If in doubt, we recommend getting in touch with the course instructor and asking them before you submit your work.

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.
