Operating Systems

A lecionação da unidade curricular será dividida em três partes: uma parte teórica com a exposição e explicação dos fundamentos teóricos, uma parte prática com resolução de exercícios, e uma parte laboratorial com a utilização de equipamentos e de software que consolide os resultados da aprendizagem.

This curricular unit aims to provide knowledge related to the structure and operation of operating systems. In particular, the acquisition of knowledge relating to the creation of processes and threads, and the different forms of intercommunication between these elements. The student should also acquire the ability to resolve problems associated with synchronization in access to resources (avoiding possible potentially conflicting requests), and with memory and storage management.

At the same time, the student will gain knowledge and experience in the installation, configuration and management of Linux distributions.

Students who successfully complete this curricular unit will be familiar with the most important aspects of operating systems operation, and will acquire the ability to develop applications that make use of an Operating System’s programming interface.
