FEKT-BOSYAcad. 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. UNIX: The kernel of the OS, its structure, calling services of the kernel. The user interface of the UNIX OS, graphical and text-based interfaces, command languages. Context switching, multitasking. Basic principles of the implementation of the UNIX OS. File systems. Management of processes, virtual memory. Basic principles of computer networks, Internet, TCP/IP. Administration and security of operating systems.

Learning outcomes of the course unit

Students are acquainted with the basic principles of operating systems (with emphasis on the UNIX operating system) and they understand the influence of operating systems upon the operation of complex computing systems. Students are able to exploit scripts for solving various tasks in a UNIX-based environment.
