Programming Concepts (algorithms and data structures) and basic concepts of operating systems use.
Students of the subject Operating Systems will acquire the knowledge and develop the skills listed below:
1. Understand the functionalities of operating systems, their structure and the relation with the rest of the computer system.
2. Know the concepts, techniques and terminology associated with the development and creation of each layer of an operating system.
3. Know how to develop software that implements these techniques.
4. Know how to express correctly, both written and orally, using the right terms.
5. Know how to develop modular and well documented software.
6. Know how to solve problems in the field of operating systems, both individually and in group.
During the academic course, the following contents will be studied:
1. Introduction to Operating systems.
2. Nucleus of an Operating system.
3. Process Planning.
4. Communication mechanisms and processes synchronization
5. Request to the UNIX system
The methodology used is based on the magisterial class and the student´s participation on it. Magisterial explanations will be given on new concepts and contents, at the same time the concepts will be linked to examples and practical problems that are to be solved either individually or in group. A large set of exercises are proposed to be solved individually or in group on the time between sessions, later this exercises will be solved, fully or partially, on following classes.
Crossed references from different parts of the subject are going to be given, with the objective of providing the student with a global vision of the whole subject, and the tools to link techniques and concepts.
Also, 12 class sessions are done in the laboratory. In each session, students carry out an activity to assimilate one of the request techniques to the programming system in C language in a UNIX system.
In the same way, a big practice is carried out structured in phases.
The methods used to evaluate the subject are the following:
A. Exams
C. Quizzes
D. Homework
F. Team reports
G. Computer assignments
J. Classroom participation
M. Others (Interviews)
The subject lasts one semester and consists of two distinct parts: the knowledge part and the project part of the subject. The evaluation of knowledge and the project will be independent. In order to pass the subject, it is necessary to pass both knowledge and project separately.
The final grade of the subject is given by the following formula:
Final_Grade = 50% · Knowledge + 50% · Project
The Knowledge grade will be evaluated from the following components: the exam grade (Exam_Grade) and the laboratory exercises grade (Lab_Grade), calculated as follows:
Knowledge = 70% · Exam_Grade + 30% · Lab_Grade
On the other hand, the exam grade (Exam_Grade) will be calculated by weighting the midterm exam (Midterm_Ex) and the final exam (Final_Ex), according to the following formula:
Exam_Grade = 80% · Final_Ex + 20% · Midterm_Ex
In addition to the final exam of the first (ordinary) call, there will be the possibility of taking a resit final exam for those students who did not pass previously (extraordinary call).
Since the Lab_Grade has a Continuous Assessment function, it will only count towards Knowledge in the first (ordinary) call. For the extraordinary call, Knowledge = Exam_Grade.
Finally, students have the option to be exempted from the final exam of the first call. To qualify for this exemption, four requirements must be met:
1.The project must be satisfactorily submitted before the first call.
2.Attendance at laboratory sessions with a grade obtained equal to or higher than 4.
3.The midterm exam grade (Midterm_Ex) must be equal to or higher than 5.
4.Attendance and participation in lecture sessions during the course.
In this case, the grade will be calculated according to the following formula:
Exemption_Grade = (55% · Project + 30% · Lab_Grade + 15% · Midterm_Ex) · Participation_Grade
The evaluation criteria for each of the objectives mentioned above are:
Objective 1:
- The student has to show knowledge on concepts and terminology linked with the subject [A, C, F, J].
- The student must be able to solve theoretical questions related with the contents of the subject [A, J]
Objective 2:
- The student must know how to interpret, analyze and solve process concurrency problems, using different techniques. [A, D, G, J].
- He must be confident with the basic techniques that apply to a system´s main memory management and know how to apply those techniques to solve problems. [A, D, G, J]
- Know the input / output subsystem and its administration. [A, C, D]
- Understand the different ways to implement a file system. [A, D, F, G]
- Understand both, in a theoretical and practical way how a system scheduler works on concurrent and distributed systems [A, C, D].
Objective 3:
- The student must be able to build the software that implements the techniques discussed during the course to solve the different tasks that an operating system must be able to perform. [A, D, G]
Objective 4:
- The student must be able to write reports using the right vocabulary for the subject [F].
- The student must be able to expose orally their work, defending design and implementation choices correctly. [M]
Objective 5:
- The student must be able to implement internally documented and well structured programs [G].
- The student must be able to write reports with detailed information on the design and implementation of the application developed [F].
Objective 6:
-The student must be able to cooperate with a team in order to sum up individual capacities [D, F, G, M].
