- Interactive analyses of the algorithms are performed in class in order to allow students to better ascertain they work.
- Mandatory
- After concluding this course the student should: Understand what is an OS and what are their objectives; Understand the main challenges when implementing an OS and be familiar with the mechanisms and algorithms that are typically used; Understand the limitations imposed by the exclusive use of the function libraries offered by the programming languages; Be able to program applications that take advantage of the services offered by the Windows OS (synchronization, inter-process communication, memory management, etc.); Understand multi-threaded application and their importance, and be able to solve basic concurrency problems; Be familiar with the basic structure of the reference OS; Understand the requirements of an OS for embedded systems and the differences to a traditional desktop or smartphone OS.
- Introduction to OS Objectives and main features Historic evolution Computer Architecture Block diagram of a typical computer OS architecture Structure and components Notions of concurrency and pseudo-parallelism Processes and threads Process Management CPU multiplexing Scheduling Interrupts Dispatcher Process Synchronization Cooperation Shared Data Critical sections Mutual exclusion Inter-process communication Shared Memory Mailboxes Sockets Memory management Real mode addressing Virtual addressing Algorithms Input/output management I/O hardware The I(O sub-system File System Basic concepts Structure Allocation methods Storage devices Protection and Security Threats Prevention Operating systems for embedded systems Static environment with limited resources In each topic will use examples using reference operating systems: Windows and Linux.
A metodologia de ensino baseia-se em aulas teóricas, nas quais são expostos os temas a abordar, aulas teórico-práticas para discussão de questões colocadas pelos alunos, realização de exercícios e apresentação de exemplos, e laboratórios onde os alunos realizam trabalhos práticos sobre as matérias abordadas.
A avaliação possui uma componente prática com base em trabalhos práticos, questionários e avaliação presencial nos laboratórios, e uma componente teórica baseada num teste escrito final . Cada componente tem um peso de 50% na nota final. Cada trabalho de laboratório tem uma sessão de discussão oral, com uma ponderação de 55% na nota de cada trabalho de laboratório.

- An operating system (OS) supplies a convenient, efficient and well defined interface between the hardware and application software. The services it provides offer the basic functionality, in any computer system, in which the application software is based. Acquiring a solid knowledge about the inner workings of the OS is of vital importance for engineering students that will enter a job market in which the development and the use of computer systems are gradually being reinforced. In particular, addressing the way an OS works, what are the main components, how to use its resources and services to develop efficient programs, and how to select an OS for a specific application, this CU supplies methodologies and abilities to think about computer systems, that are very broad and useful even for a career not connected to development.
