Trataremos de cubrir tanto os conceptos como as distintas implementacións deses mesmos conceptos empregando sistemas nas distintas ramas da árbore da familia Unix Suponse un certo coñecemento dos conceptos básicos do sistema operativo, ordes básicos unix e programación do shell.
Contingency plan	1. Modificacións nos contidos ningunha 2. Metodoloxías *Metodoloxías docentes que se modifican - Sesión maxistral: videoconferencia - Prácticas: supervisadas a través das TIC, - Proba obxectiva e proba práctica: a través de Moodle, Teams u outra ferramenta de UDC. - Traballos tutelados: Dada as dificultades para reunirse facer os traballos en grupo,realizar as exposicións na clase e as evaluación peer to peer, a realización de traballos sustituirase pola realización de memorias das prácticas feitas 3. Mecanismos de atención personalizada ao alumnado - Moodle: se suministrarán todos os recursos docentes a través do moodle e a paxina web da asignatura. - Teams u outra ferramente de videoconferencia. Póderan convocarse sesións de teams para a titorización - Correo electrónico: para calquera dúbida 4. Modificacións na avaliación De acordo coa modificación das metodoloxias correspondente aos traballos tutelados, a parte correspondente aos traballos tutelados engadirase a parte das prácticas, concretamente a realizacion das memorias das mesmas *Observacións de avaliación: No caso de non poder ser presencial: Tanto a proba obxectiva como a proba práctica se farán mediante teams, moodle ou outra ferramenta da udc 5.

Methodologies

Methodologies	Description
Guest lecture / keynote speech	The teacher will elaborate on the contents and give guidance on how to use and apply these concepts in the laboratory
Laboratory practice	Practical application of the concepts exposed in the magisterial sessions. The students will install several different unix systems (System V, BSD. POSIX ...) on the same virtualized machine, having to coexist the different types of partitions and the different boot loaders and will carry out the different administration tasks of the S.O. on each of the installed systems
Supervised projects	Preparation and exposition in class, by the students, of complementary topics to the syllabus of the subject
Objective test	Written exam to evaluate the degree of assimilation of the concepts exposed in the master sessions

Personalized attention

Methodologies Objective test Supervised projects Guest lecture / keynote speech Laboratory practice

Description An attempt will be made to resolve all doubts and make as many clarifications as necessary in the classroom hours in the different methodologies. In addition, the teacher will be available for personalized attention to students in the tutoring hours reserved for this purpose. Students have the possibility of reviewing the evaluations obtained in the different sections and being informed of the criteria that have been used for this purpose.

Assessment

Methodologies	Competencies	Description	Qualification
Objective test		Written exam to assess the degree of assimilation of the concepts exposed in the master sessions	40
Supervised projects		Both their contents as well the expositions in class will be evaluated. Students not taking part in the class presentations, will perform peer to peer evaluations of the expositions and must prove the adquisition of the bascic concepts used in them	20
Laboratory practice		The delivery of the practices in the pre-established deadline will be valued as well as its correct operation. Furthermore, as part of the practice evaluation process, an individual practice exam could be carried out, either on one of machines used in the practical classes or on a machine specifically provided for this purpose. STUDENTS PART TIME: A meeting will be held at the beginning of the course to assess how the evaluation will be carried out based on its availability	40
