Course detail
Operating Systems
FIT-IOSAcad. year: 2017/2018
The concept of an operating system (OS) as a part of software of a computer system. Architectures of operating systems, a classification of operating systems. An overview of the contemporary operating systems. The kernel of UNIX, its structure, graphical and textual interfaces, command languages. Process management, context switching, scheduling, interprocess communication. Memory management, paging, virtual memory. Synchronization of processes, semaphores and other synchronization means, deadlock, starvation.

- Syllabus of lectures:
- Introduction. Evolution of computers and operating systems (OS). Requirements on OS, classification of OS, standards. The basic terminology and the general structure of OS.
- The UNIX operating system. The history and the most important development branches. The basic principles and structure of UNIX. The structure of the UNIX kernel, its interface and the different forms of communication with the kernel.
- UNIX shell. Basic commands, programs, scripts. Special symbols. Input/output redirection, pipes, background processes, sub-shell. Variables, control structures.
- A basic introduction to programming in UNIX. Languages, compilers, principles of linking programs, dynamically linked libraries. Principles of the X-Window graphical user interface.
- Standard utilities of UNIX.
- File systems. The physical and logical structure of disks. Types of files, i-nodes, storing files on a disk.
- Access rights to files in UNIX, users and groups, the suid and sgid attributes, the typical structure of directories in a UNIX system.
- Input and output. The corresponding kernel services. Data structures and algorithms used by the input/output subsystem of the kernel.
- Management of processes. Loading the system, the init process. Fork, exec, exit, and wait calls. States of processes, scheduling.
- Memory management. Address spaces, address translation, memory pages.
- Virtual memory.
- Mutual exclusion, semaphores and other synchronization means.
- Typical synchronization tasks, deadlocks, starvation.
- Creating scripts by means of UNIX shell and the standard utilities of UNIX.
