Objectives and Contents
Objectives of the Course Unit This course will introduce the core concepts of operating systems, such as processes and threads, scheduling, synchronization, memory management, file systems, input and output device management and security
Contents of the Course Unit GENERAL LEARNING OUTCOMES (COMPETENCES) On successful completion of this course, all students will have developed knowledge and understanding of: 1- hardware support for operating systems: privileged mode execution, saving and restoring CPU state, traps and interrupts, timers, memory protection. Operating system techniques for protecting user and hardware resources. Overview of the key operating system abstractions and the use of system calls to manipulate them. 2- Program execution, the process concept, process-related state, the process table, saving and restoring process state, the role of the scheduler 3-Threads, process context switch vs thread switch, true concurrency vs pseudo concurrency, operating systems as concurrent programs, concurrency through multi-threading, concurrency through interrupt handling, concurrent access to shared memory, race conditions, mutual exclusion, synchronization primitives based on atomic instructions 4- locks, spinlocks, mutex semaphores, counting semaphores, and their use in solutions to Producer Consumer synchronization 5- Classic synchronization problems: Producer Consumer, Dining Philosophers, Readers and Writers, Sleeping Barber. 6- Monitors, condition variables, message passing, and their use in solutions to classic synchronization problems: Producer Consumer, Dining Philosophers, Readers and Writers, Sleeping Barber 7- Deadlock, livelock, deadlock detection, avoidance, and prevention 8-Separation of policy from mechanism, scheduling mechanisms, preemptive vs non-preemptive scheduling, example scheduling policies, FIFO, round-robin, shortest job first, priority scheduling, Unix-style feedback scheduling, proportional share scheduling, lottery scheduling 9- Memory addresses and binding, static and dynamic addresses translation, address translation using base and limit registers, memory management algorithms using linked lists and bitmaps, external and internal fragmentation, paged virtual memory. 10- Physical address spaces, virtual address spaces, page table design, single-level and multi-level page tables, hardware support for dynamic address translation using a TLB, hardware and software managed TLB refill 11- Demand paging, swapping, placement and replacement algorithms, memory hierarchy revisited, overview of cache architecture, performance modeling for memory management systems 12- Devices, memory mapped devices, DMA, device drivers, interrupt handling, scheduled vs non-scheduled I/O processing, block vs character devices 13- Disks, sectors, tracks, blocks, disk head scheduling algorithms, the file abstraction, directories, links 14- File system architecture, file system data structures and system calls
Contribution of the Course Intending to Provide the Professional Education On successful completion of this course, all students will have developed knowledge and understanding of modern operating systems.

EBS : Kıbrıs İlim Üniversitesi Eğitim Öğretim Bilgi Sistemi Kıbrıs İlim Üniversitesi AKTS Bilgi Paketi AKTS Bilgi Paketi ECTS Information Package Avrupa Kredi Transfer Sistemi (AKTS/ECTS), Avrupa Yükseköğretim Alanı (Bologna Süreci) hedeflerini destekleyen iş yükü ve öğrenme çıktılarına dayalı öğrenci/öğrenme merkezli öğretme ve öğrenme yaklaşımı çerçevesinde yükseköğretimde uluslarası saydamlığı arttırmak ve öğrenci hareketliliği ile öğrencilerin yurtdışında gördükleri öğrenimleri kendi ülkelerinde tanınmasını kolaylaştırmak amacıyla Avrupa Komisyonu tarafından 1989 yılında Erasmus Programı (günümüzde Yaşam Boyu Öğrenme Programı) kapsamında geliştirilmiş ve Avrupa ülkeleri tarafından yaygın olarak kabul görmüş bir kredi sistemidir. AKTS, aynı zamanda, yükseköğretim kurumlarına, öğretim programları ve ders içeriklerinin iş yüküne bağlı olarak kolay anlaşılabilir bir yapıda tasarlanması, uygulanması, gözden geçirilmesi, iyileştirilmesi ve bu sayede yükseköğretim programlarının kalitesinin geliştirilmesine ve kalite güvencesine önemli katkı sağlayan bir sistematik yaklaşım sunmaktadır. ETIS : İstanbul Aydın University Education & Training System Cyprus Science University ECTS Information Package ECTS Information Package European Credit Transfer and Accumulation System (ECTS) which was introduced by the European Council in 1989, within the framework of Erasmus, now part of the Life Long Learning Programme, is a student-centered credit system based on the student workload required to achieve the objectives of a programme specified in terms of learning outcomes and competences to be acquired. The implementation of ECTS has, since its introduction, has been found wide acceptance in the higher education systems across the European Countries and become a credit system and an indispensable tool supporting major aims of the Bologna Process and, thus, of European Higher Education Area as it makes teaching and learning in higher education more transparent across Europe and facilitates the recognition of all studies. The system allows for the transfer of learning experiences between different institutions, greater student mobility and more flexible routes to gain degrees. It also offers a systematic approach to curriculum design as well as quality assessment and improvement and, thus, quality assurance.
