OVERVIEW

The purpose of this course is first to learn how operating systems work and how to administer and interact with them, and second to examine the mechanisms used to create networks of computers that communicate with each other and learn how to exploit them through programming.

AIMS AND CONTENT

LEARNING OUTCOMES

Acquire techniques for the design, implementation, and efficient and secure management of computing and distributed systems:

• at the operating system level, focusing on multitasking execution, support for concurrency, cooperation and synchronization between threads and processes, I/O management, file management, and computer virtualization;
• at the modern computer network level, to evaluate the reliability, security, and manageability features resulting from protocol design choices.

AIMS AND LEARNING OUTCOMES

• Know how to interact with the operating system via command line.
• Describe how file systems work.
• Know how to use system primitives 
• Know how to explain the use of memory
• Know how to configure an operating system
• Describe the main network architectures
• Explain the operation of IP, TCP, DHCP, DNS network protocols
• Analyze TCP/IP-based data packets.
• Implement networks of computers communicating via sockets (both UDP and TCP)
• Know how to implement multi-threaded systems
• Know how to recognize the risks due to the use of concurrency

PREREQUISITES

• Familiarity with the C/C++ language
• Knowledge of computer architecture

EXAMS

EXAM DESCRIPTION

The exam consists of a quiz, a written test and a programming project to be presented during an oral. In order to take the written test, it is necessary to have passed the quiz. To be able to discuss the project, it is necessary to have passed the written test.

Guidelines for students with certified Specific Learning Disorders, disabilities, or other special educational needs are available at https://corsi.unige.it/en/corsi/8759/studenti-disabilita-dsa 

ASSESSMENT METHODS

The written test verifies the student's knowledge of the main theoretical concepts presented in class and the student's ability to apply them to the proposed exercises. The project delves into verifying that the student is able to put them into practice through programming.
