An operating system is a set of programs that act as an intermediary between a user of a computer, the computer hardware and the applications programs. The purpose of an operating system is to provide an environment in which a user can execute programs in a convenient and efficient manner.

1. write an multithreaded program and program which creates multiple processes
2. demonstrate how interrupt service routine works
3. apply synchronization mechanisms
4. list components of operating system kernel
5. analyze deterministic and non-deterministic task system behaviour
6. list and explain CPU scheduling algorithms
7. employ memory allocation mechanisms
8. explain demand paging
9. develop file-system functions
