General skills:



[C1] To acquire the required basic theoretical knowledge needed to understand the basis of data transmission services.

[C2] To understand and use the protocol’s architecture concept, based on OSI as paradigmatic model.

[C3] To know the main network technologies and use them efficiently to create small networks.

[C4] To know the basis of Internet: protocols, access ways and most used services



Competencies in the computer science branch:



M02CM05 - Knowledge, management and maintenance of computing systems, services and applications.

M02CM011 - Knowledge and application of the features, functionalities and structure of Distributed Systems, Computer Networks and Internet, and design and implement applications based on them.

M02CM018 - Knowledge of computing’s normative and regulation in national, european and international scopes.

BASIC CONCEPTS: NETWORK TYPES, CLASSIFICATION, REFERENCE MODELS AND PROTOCOLOS.

Overview of the basic concepts of computer networks: physical transmission of information, types of devices, protocol and services protocol architecture and network types.



REFERENCE MODELS AND PROTOCOLS.

Study of the concept of protocols and services architecture, with the OSI reference model as paradigm due to the easy approach it provides to understand the Internet TCP/IP protocol stack.



APPLICATION PROTOCOLS

Analysis of the application protocols most used currently in computer networks (HTTP, SSH, etc) and of the most usual programs that implement them.



NETWORK AND TRANSPORT LAYERS: TCP/IP MODEL.

Overview of Internet networks’ fundamentals. Analysis in depth of IP and TCP along with other protocols related to them (ARP, DHCP, DNS).



LINK LAYER AND FUNCTIONS.

The objective of the link layer is to allow the flow without errors between two machines, point-to-point. This layer’s most common functions and protocols are studied.



PHYSICAL LAYER. DATA TRANSMISSION. TRANSMISSION MEDIA.



Success on transmission depends on the quality of the transmitted signal and of the transmission media’s features. The analysis of the signal types and transmission and physical media allows to understand that dependency



LOCAL AREA NETWORKS.

Identification and study of the most relevant features of the local area networks: transmission media, transmission mode, topology, and access media techniques.



WIRELESS NETWORKS

Study of the most used protocols in wireless networks. Examples of creation of a wireless network using the resources of Linux operative system.



COMMUNICATIONS SECURITY

The needs of communications security through networks are studied. The configuration of a firewall with “iptables” is shown.

Theory class: The concepts needed are explained both to achieve the knowledge objectives and as a tool to allow free discussion and generate curiosity among the students.



Classroom practices: Used for exercises, problems and work exhibition. Students’ participation is facilitated.



Laboratory practices: Practice sessions will allow the practice of the knowledge acquired in the theory sessions and its application to real problems.

a) Continuous Evaluation:



- Written exam with a value of 60% of the final grade. The exam will be carried out in a test that will coincide with the Ordinary Call of the Center. It will be necessary to pass this exam to be able to do average.

- The rest of the evaluation activities will have a value of 40% of the final grade: laboratory practices (20%), group and individual activities (20%).



b) Final Evaluation (for students who request it):



It will consist of a single final test that will correspond to 100% of the final grade for the subject and will coincide with the Ordinary Call of the Center. This final test will have a written part (60% of the final grade) and a practical part to be done in the laboratory (40% of the final grade). It will be necessary to pass both parts of the final test.



To apply for the final assessment system (b), students must submit their waiver of continuous assessment in writing to the teaching staff responsible for the subject. There will be a period of 9 weeks to present the resignation from the beginning of the four-month period.



Resignation of the students to a call:



In the case of continuous assessment, students may withdraw from the call within a month before the end date of the course's teaching period. This resignation must be submitted in writing to the teaching staff responsible for the subject.



In the case of a final evaluation, failure to take the test set on the official exam date will mean the automatic resignation of the corresponding call.

Transparencies and notes of the subject (practice scripts, exercises, auxiliary documents).
