• ObjectivosObjectives

  The main goal of this curricular unit is to provide students with technical and practical skills in information systems administration, enabling them to configure, manage and maintain operating systems and services in local and networked environments, with a focus on security and reliability. By the end of the unit, students should be able to: Understand the fundamental principles of operating systems and system administration. Install, configure and manage Linux systems in physical and virtualized environments. Use the command line to manage files, users, permissions, processes and services. Configure basic networks and services and perform maintenance and monitoring tasks. Apply good administration and security practices. Work autonomously and collaboratively to solve technical problems.

• MetodologiaMethodology

  The curricular unit adopts practice-oriented and problem-based learning methodologies focused on real-world system administration scenarios. Classes combine theoretical exposition with laboratory activities, fostering the progressive configuration of Linux systems, virtualized environments and network services. Innovative approaches include project-based and problem-based learning, the use of virtual environments to simulate real infrastructures and the application of administrative and collaborative tools. Students are encouraged to experiment, document and reflect on the adopted procedures, fostering autonomy, critical thinking and teamwork.
