Objectives

At the end of the semester, students should be capable of:
- describing the functions and structure of an operating system and identifying its main abstractions;
- understanding the functioning of the main components of an operating system, the way they interact with each other and the main algorithms used to implement them;
- using and exploring the application programming interface (API) and of a real operating system (UNIX/LINUX).

Program

INTRODUCTION TO OPERATING SYSTEMS

- Hardware support and protection requirements

PROCESS MANAGEMENT
- Processes and threads; process status
- Scheduling strategies
- Concurrent execution: problems and solutions
- Synchronization mechanisms between processes
- Deadlocks

MEMORY MANAGEMENT
- Basic memory management: overlays, swapping and partitions
- Virtual memory systems: paging and segmentation
- Implementation of virtual memory; strategies for memory allocation/ release

INPUT/OUPUT SYSTEMS
- Input/output hardware and software
- Abstraction of differences between devices

FILE SYSTEMS
- File-system interface
- File-system implementation; disk management

SYSTEM PROGRAMMING (API, UNIX/LINUX) - covered along the course
- file and directory manipulation
- creation and control of processes and threads
- communication and synchronization among processes and threads

Software

Teaching methods and learning activities

-Theoretical classes: presentation of the themes of the course, based on the exercise resolution
- Practical classes: resolution of programming exercises using API of Unix/Linux
- Practical assignments: to be done out of the class period using the API.

Eligibility for exams

To be admitted to exams students have to attend to 75% of the classes and have to achieve a minimum mark of 40% in the practical assignments.
Coutinuous Assessment= 0.5*AG1 + 0.5*AG2 (AG1 and AG2- Assignment grade)
Even though practical assignments are group assignments, students can be graded in a different way, depending on the professor opinion regarding their performance.
Students, who have attended to this course last year and have a passing mark in the continuous assessment component, can have the same grade and do not need to attend classes and to do the practical assignments. However, they need to inform the professor at the beginning of the semester.

Calculation formula of final grade

Final Mark= 0.5*CA + 0.5 *FE (CA- Continuous assessment; FE- Final Exam)
To complete the course, students have to achieve a minimum mark of 40% in both components.

Special assessment (TE, DA, ...)

Students with a special status will be assessed in the same way as ordinary students. They have to do all the assignments and deliver them on the scheduled dates.

Classification improvement

Students can only improve the mark of the continuous assessment component in the following year.
Students can improve the mark of the written exam at the corresponding seasons (according to the rules).

Observations

Previous knowledge: C programming language.
Groups are composed by two students, and exceptionally three students.
