Obs.: Se houver alunos inscritos não fluentes em Português, as aulas e as provas, na generalidade, serão em Inglês.

Objectives

The main objectives of this curricular unit are to provide the fundamental knowledge on:
O1- the structure and the operation of a generic operating system;
O2- the use of the Application Programming Interface (API) of a real operating system.

Learning outcomes and competences

The students who complete successfully this curricular unit should be able to:
LO1- describe the functions and the general structure of an operating system and identify the main abstractions that it provides;
LO2- describe the operation of the essential components of an operating system, the way they interact and the fundamental algorithms used to implement them;
LO3- develop programs using and exploring the API of an Unix-type operating system.

Working method

B-learning

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Previous knowledge of programming with the C language is required. Approval in the curricular unit of "Programming" is recommended.

Program

INTRODUCTION TO OPERATING SYSTEMS
- Objectives and functions of an operating system
- Abstractions supported and their programming interface
PROCESS MANAGEMENT
- Processes and threads
- Concurrent execution: problems and solutions
- Synchronization mechanisms between processes/threads
MEMORY MANAGEMENT
- Basic physical memory management
- Virtual memory: need and management mechanisms
INPUT/OUPUT SYSTEMS
- hardware and software
- Abstraction of differences between devices (to the user and the programmer)
FILE SYSTEMS
- File-system importance and interface to the user and the programmer
- File-system internal structure and storage on "durable" devices

Complementar practical part (covered along the course )
SYSTEM PROGRAMMING (UNIX/LINUX API)
- File and directory manipulation
- Process and thread creation and management
- Interprocess communication: signals, pipes, FIFOs, and shared memory
- Process and thread synchronization: semaphores, mutexes and condition variables

Teaching methods and learning activities

- Theoretical classes: presentation and discussion of the subject matter, accompanied by the resolution of small illustrative exercises.
- Theoretical/practical classes: resolution of programming exercises involving the use of the Unix/Linux API.
- Self-learning: study of the programme themes, using the bibliography and the materials available at the web page of the curricular unit; resolution of exercises and development of two projects, involving the use of the API.

Eligibility for exams

The continuous assessment grade (NotFreq) results from the expression:
   NotFreq =  0.4 * NotMP1 + 0.3 * NotMP2a + 0.3 *NotMP2b
where
   NotMP1 - grade of the 1st assignment
   NotMP2a, NotMP2b - grades of the 2nd assignment, respectively, of its 1st part and of its 2nd part

Remarks:
1- To be admitted to exams, students have to achieve a minimum mark of 40% of the continuous assement grade and to have attended at least 75% of the practical classes.
2- Although the mini-projects are carried out by students in a group, members of the same group may have a different classification in any of the works: this will depend on the opinion of the teacher and the self-assessment within the group.
3- Students who have attended to this course last year and have a passing mark in the continuous assessment component can keep the previous grade; in this case, they need to inform the teacher during the first week of the semester and should not enroll in the practical classes.

Calculation formula of final grade

The final mark (NotFinal) results from the expression:
   NotFinal =  0.5 * NotFreq + 0.5 * NotExam
where
   NotFreq - grade of the continuous assessment
   NotExam - grade of the final exam

However, in order to pass the course unit a minimum grade in the written exam of 40% of the scale is required.

Special assessment (TE, DA, ...)

Students with special status are subject to the same assessment conditions as regular students, except that they are exempt from attending practical classes.
Special-season exams are therefore equivalent to the written exams of normal and resit periods for regular students.

Classification improvement

The overall grade of the practical works can only be improved in the following academic year.
The grade of the written exam can be improved in the exam seasons legally provided.

Observations

If in person, the individual written exam will be done without consultation of any documentation other than that provided by the teacher.
Very important: cases of dishonest academic conduct will be presented to the Course Director.
