Teaching, Attendance, Course Books and Assessment
- Teaching
Theory lectures and laboratory exercises, both face-to-face and on-line.
- Attendance
Although recommended, course attendance is not mandatory.
- Course books
Silbershatz, Galvin, Gagne, "Sistemi Operativi Concetti ed Esempi", Pearson
Tanenbaum, "I Moderni Sistemi Operativi", Pearson
Ancilotti, Boari, "Programmazione Concorrente e Distribuita", McGraw-Hill.
Bovet, Cesati, "Understanding the Linux Kernel", O'Reilly
Goetz, Peierls, Bloch, Bowbeer, Holmes, Lea, "Java Concurrency in Practice", Addison-Wesley
- Assessment
Individual project, written exam and oral exam.
The individual project, which has to be submitted at least seven days before the written exam, is passed if the mark (which is valid for all the exam calls on the academic year) is at least 18/30.
The written exam, which can be taken only if the project is passed, is passed if the mark (which is valid for all the exam calls on the academic year) is at least 18/30.
The oral exam, which can be taken only if the project and the written exam are passed, determines a spread between -10/30 and 10/30 of the average of the two previous marks, thus yielding the final mark.
- Disabilità e DSA
Le studentesse e gli studenti che hanno registrato la certificazione di disabilità o la certificazione di DSA presso l'Ufficio Inclusione e diritto allo studio, possono chiedere di utilizzare le mappe concettuali (per parole chiave) durante la prova di esame.
A tal fine, è necessario inviare le mappe, due settimane prima dell’appello di esame, alla o al docente del corso, che ne verificherà la coerenza con le indicazioni delle linee guida di ateneo e potrà chiederne la modifica.
Notes
The course is offered both face-to-face and on-line within the Laurea Degree Program in Applied Computer Science.
