There are two types of exercises: drastiriotites (activities) and frontistiriakes (tutorial exercises).

In the activities:

• The first two are based on xv6 (folder xv6-master).
• The remaining activities use the Linux source code. Each folder (OS_drastiriotita1 to OS_drastiriotita5) contains a detailed report of the exercise with screenshots highlighting the code modifications for each requirement, along with explanations(e.g. about system calls, interrupts, etc). Activity 5 also includes the source code showcasing the functionality of the developed driver.

In the tutorial exercises, code is provided for tasks involving threads and processes.
