The goal of this course is to introduce basic concepts and principles of operating systems (OS), like processes and threads, their scheduling, mutual communication and synchronization, time-dependent errors and deadlocks. Attention is also paid to memory management, virtual memory, management of secondary storages, file-systems and data security. The second part of the course is focused at distributed systems (DS) principles and technologies. DS communication media and topologies are explained and the basics of Internet including specific protocols are treated as typical DS applications.

Study targets:

Cílem předmětu je seznámit posluchače se základními pojmy a principy operačních systémů a počítačových sítí

Course outlines:

1. Basic concepts: operating system (OS) and its kernel, hardware dependency, processes, threads, scheduling. OS types.
2. Compiling and linking, libraries, OS services and calls, dynamic libraries and run-time linking
3. Implementation and life-cycle of processes and threads. Scheduling algorithms. Real-time OSes and scheduling in them.
4. Communication among processes and threads, critical sections, time-dependent errors, synchonization tools. Classical synchronization problems and their solution.
5. Deadlocks: definition, conditions, solution possibilities
6. Memory management: Basic techniques. Virtual memory, swapping, paging, segmentation, page-replacement algorithms.
7. File-systems, organizing data on the secondary storage, principles, standard solutions, data security.
8. Distributed computing, client-server architectures. OS components supporting computer networks (sockets) and their programming.
