OS3216.2 Operating Systems, 3 credits
Prerequisites: "Informatics", "Algorithms, data structures and programming," "Programming
technology", any knowledge of one of programming languages for writing programs.
The purpose of the study: This course is an introductory course into operating system design and
implementation. The operating system provides a well-known, convenient, and efficient interface
between user programs and the bare hardware of the computer on which they run. The operating
system is responsible for allowing resources (e.g., disks, networks, and processors) to be shared,
providing common services needed by many different programs (e.g., file service, the ability to start
or stop processes, and access to the printer), and protecting individual programs from one another.
The course will start with a brief historical perspective of the evolution of operating systems over
the last fifty years, and then cover the major components of most operating systems. This discussion
will cover the tradeoffs that can be made between performance and functionality during the design
and implementation of an operating system. Particular emphasis will be given to three major OS
subsystems: process management (processes, threads, CPU scheduling, synchronization, and
deadlock), memory management (segmentation, paging, swapping), file systems, and operating
system
support
for
distributed
systems.
Summary: Introduction, Operating Systems history. Processes, threads and dispatching. Process
Management. Concurrent threads. CPU Scheduling. Synchronization: Locks and condition
variables. Implementing locks. Semaphores. Deadlock. Linking and dynamic linking. Monitors and
condition variables. Readers and writers. Dining philosophers. Memory management. Relocation.
Memory management: paging. Segmented paging. Demand paged virtual memory. File systems.
File system implementation. Secondary storage, disks. I/O systems, device drivers. Communication
and
networking.
Distributed
systems
and
RPCs.
NFS,
protection.
Expected results: You will have an opportunity to learn a lot of practical information about how
programming languages, operating systems, and architectures interact and how to use each
effectively. This course is the first time when you will learn about how concurrency and distributed
systems communicate and work correctly. This knowledge will help you to more effectively use
and manipulate computers and computer programs. Written and programming assignments are
designed to build on and enhance the lectures. You will hear the concepts in lecture, read them in
the presentations and/or from handouts/ pdf-files, analyze them in the written homework, and put
them in practice in the programming assignments. You will understand more detailed main
principles of how OS work, and how processes intercommunicate with each other, scheduling the
resources
and
processes,
deadlock,
and
preventing
such
situations.

Post requisites: ―Computer security‖, "Computer networks", "Design of Information Systems",
―Implementation of client-server applications‖.
