In this subject, students learn the services and utilities offered by operating systems, as well as about the management of the resources they offer.
Specific Bachelor Computer Engineering
• Competence to evaluate technological solutions and write project proposals
taking into account the available resources, the alternatives and the market
• Competence to analyze a problem at the appropriate level of abstraction and
apply the skills and knowledge gained in the degree to solve it.
• Competence to identify the structural elements and the working principles of a
• Competence to manage the operating systems and the communication
infrastructure of a computer network.
• Competence to design and build computer applications by using development,
integration and reusability techniques.

• Learn the services provided by an OS from user, programmer, and system administrator viewpoints.
• Learn how to use the various systems for interacting with the OS (commands, scripts, libraries, system calls, etc.) and their implementation.
• Learn how to describe the requisites of a file system and the services it should offer. Learn the various implementation methods in current systems (partitions, FAT, i-nodes, NTFS, RAID).
• Learn the input/output operations that an OS should provide to programmers. Ability to describe device concepts and needs, and management and implementation of devices (partly dependent and partly independent, device descriptors, etc.).
• Learn the concepts of processing, multi-processing, shared time, concurrence, and threads. Learn the problems that can arise from the use of processes and threads, and ways of solving them. Learn to manage processes and threads. Learn how to describe implementation of these concepts on current systems.
• Learn about synchronisation and communication mechanisms between processes/threads (such as pipes, named pipes, shared memory, traffic lights, etc.) and how to use them.
• Learn how to describe and manage events and exceptions. Implementations.
• Learn how to describe the most basic concepts regarding operating systems and computer networks. Learn how to use sockets. Link OS and network concepts.

• Learn the basic notions regarding OS performance and optimization techniques.
• Use and application of Information and Communication Technologies (ICT) in academic and professional environments.
• Ability to adapt to future technologies and environments by updating their
• Ability to innovate and generate new ideas.
Any professional practice related with the bachelor will need the knowledge related to hardware. Therefore, the additional objective of the course is to learn necessary concepts to understand what a computer is taking into account its management through the main components of the operating system and to be able to develop any professional activity using it.

The material of the course will remain available in electronic format. A couple of electronic books and guidelines will lead the course.
The student can find the operating system GNU/Linux to install within the Virtual classroom. A link will be available to install GNU/Linux.
Guidelines' Shell and calls system can be found in the space of Resources of the Virtual Classroom.
The assessment process is based on the student's personal work and presupposes authenticity of authorship and originality of the exercises completed.
Lack of authenticity of authorship or originality of assessment tests, copying or plagiarism, the fraudulent attempt to obtain a better academic result, collusion to copy or concealing or abetting copying, use of unauthorized material or devices during assessment, inter alia, are offences that may lead to serious academic or other sanctions.
Firstly, you will fail the course (D/0) if you commit any of these offences when completing activities defined as assessable in the course plan, including the final tests. Offences considered to be misconduct include, among others, the use of unauthorized material or devices during the tests, such as social media or internet search engines, or the copying of text from external sources (internet, class notes, books, articles, other students' essays or tests, etc.) without including the corresponding reference.
And secondly, the UOC's academic regulations state that any misconduct during assessment, in addition to leading to the student failing the course, may also lead to disciplinary procedures and sanctions.
The UOC reserves the right to request that students identify themselves and/or provide evidence of the authorship of their work, throughout the assessment process, and by the means the UOC specifies (synchronous or asynchronous). For this purpose, the UOC may require students to use a microphone, webcam or other devices during the assessment process, and to make sure that they are working correctly.
The checking of students' knowledge to verify authorship of their work will under no circumstances constitute a second assessment.
