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.

Objectives
Objectives
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.
