The teaching is organized as follows:

Learning outcomes

The aim of the course is to provide the theory and practice at the basis of the organization of a com-puter system and of the operating systems running on it, with the related issues of correctness and efficiency. The course provides the basics for the design, implementation, development, manage-ment and maintenance of hardware and software systems in biotechnological laboratories. At the end of the course, the students will be able to write shell scripts using system calls in C in the UNIX environment; manage an information system, especially for what the installation and mainte-nance of applications and resources is concerned; and use network analysis software and IT tools to support biology and medicine laboratories. The course is structured on two modules: Elements of operating systems and Elements of computer networks

Program

Theory
----------

* Operating systems
- Operating system architectures
- Starting the operating system
- Organization of mass storage
- File system
- Process scheduling
- Concurrency

* Networks
- The problem of communication
- Fundamental concepts
- The ISO/OSI model
- The physical layer
- The datalink layer
- The network layer
- The transport layer
- The application layer
- Fundamental concepts of network security

Laboratory
-----------------

* Operating systems
- Programming using the UNIX shell
- Programming using UNIX system calls

* Networks
- network analysis tools
- network programming through web services
- models for distributed computing

Examination Methods

To pass the exam, the student must show:
- they have understood the principles related to operating systems
- they have understood the principles related to the communication between systems
- they are able to describe the concepts in a clear and exhaustive way without digressions
- they are able to apply the acquired knowledge to solve application scenarios described by means of exercises, questions and projects.

The final evaluation is the arithmetic mean of the grade obtained for the Elementi di Sistemi Operativi module and of that for the Elementi di Reti module. For Elementi di Sistemi Operativi, the final exam consists of a written test containing questions and exercises for the Theory and, for the Laboratory, of a written test covering programming skills acquired during the course or, alternatively, some projects to be completed during the course. For Elementi di Reti, the final exam consists of an oral test on a computer with questions on both theory and laboratory.
