About this Course. The core of the course contains concurrent programming (threads and synchronization), inter process communication, and an introduction to distributed operating systems. The course is split into four sections: (1) Introduction, (2) Process and Thread Management, (3) Resource Management and Communication, and (4) Distributed Systems.
Operating System courses from top universities and industry leaders. Learn Operating System online with courses like 操作系统原理（Operating Systems） and Operating Systems and You: Becoming a Power User.
Take classes on operating systems online to learn everything from Linux and Mac OS, to Microsoft and more. Choose from beginner to advanced courses.
Course Description. This class introduces the basic facilities provided in modern operating systems. The course divides into three major sections. The first part of the course discusses concurrency: how to manage multiple tasks that execute at the same time and share resources.
This free Introduction to Operating Systems course is perfect for those who have already gained an understanding of C programming, computer organisation, and computer architecture. By the end of this course, you will have studied the functions of the computer OS, the CPU, hardware addresses, and much more.
To take up this operating system course you must have a degree and be familiar with basic hardware and software aspects of the organization. You can have prior programming experience with C which is recommended. Fresher’s and STEM graduates with a passion to know more about OS can take up the course.
We will begin this course with a high level introduction to Operating Systems (OS). The Operating System acts as a platform of information exchange between your computer's hardware and the applications running on it.
Now that we have completed the course, what can you do next? We will discuss a list of courses that you can look into to further enchance your knowlege of the Linux operating system while developing the technical capabilities to pass a professional Linux certification.
This page is a glossary of Operating systems terminology. 1. A ---- access token: In Microsoft Windows operating systems, an access token contains the security credentials for a login session and identifies the user, the user's groups, the user's privileges, and, in some cases, a particular application. 2. B ---- binary semaphore: See semaphore. booting: In computing, booting (also known as booting up) is the initial set of operations that a computer system performs after electrical power to the CPU is switched on or when the computer is reset. On modern general purpose computers, this can take tens of seconds and typically involves performing a power-on self-test, locating and initializing peripheral devices, and then finding, loading and starting the operating system. 3. C ---- cache: In computer science, a cache is a component that transparently stores data so that future requests for that data can be served faster. The data that is stored within a cache might be values that have been computed earlier or duplicates of original values that are stored elsewhere. cloud: Cloud computing operating systems are recent, and were not mentioned in Gagne's 8th Edition (2009). In contrast, by Gagne's 9th (2012), cloud o/s received 3 pages of coverage (41, 42, 716). Doeppner (2011) mentions them (p. 3), but only to prove that operating systems "are not a solved problem" and that even if the day of the dedicated PC is waning, cloud computing has created an entirely new opportunity for o/s development ala sharing, networks, memory, parallelism, etc. Gagne (2012) adds that in addition to numerous traditional o/s's at cloud warehouses, Virtual machine o/s (VMMs), Eucalyptus, Vware, vCloud Director and others are being developed specifically for cloud management with numerous traditional o/s features (security, threads, file and memory management, guis, etc.) (p. 42). Microsoft's investment in cloud aspects of o/s tend to support that argument. concurrency 4. D ---- daemon: Operating systems often start daemons at boot time and serve the function of responding to network requests, hardware activity, or other programs by performing some task. Daemons can also configure hardware (like udevd on some Linux systems), run scheduled tasks (like cron), and perform a variety of other tasks. 5. E ---- 6. F ---- 7. G ---- 8. H ---- 9. I ---- 10. J ----- 11. K ----- kernel: In computing, the kernel is a computer program that manages input/output requests from software and translates them into data processing instructions for the central processing unit and other electronic components of a computer. The kernel is a fundamental part of a modern computer's operating system. 12. L ----- lock: In computer science, a lock or mutex (from mutual exclusion) is a synchronization mechanism for enforcing limits on access to a resource in an environment where there are many threads of execution. A lock is designed to enforce a mutual exclusion concurrency control policy. 13. M ----- mutual exclusion: Mutual exclusion is to allow only one process at a time to access the same critical section (a part of code which accesses the critical resource). This helps prevent race conditions. mutex: See lock. 14. N ----- 15. O ----- 16. P ----- paging daemon: See daemon. process 17. Q ----- 18. R ----- 19. S ----- semaphore: In computer science, particularly in operating systems, a semaphore is a variable or abstract data type that is used for controlling access, by multiple processes, to a common resource in a parallel programming or a multi user environment. 20. T ----- thread: In computer science, a thread of execution is the smallest sequence of programmed instructions that can be managed independently by an operating system scheduler. The scheduler itself is a light-weight process. The implementation of threads and processes differs from one operating system to another, but in most cases, a thread is contained inside a process. templating: In an o/s context, templating refers to creating a single virtual machine image as a guest operating system, then saving it as a tool for multiple running virtual machines (Gagne, 2012, p. 716). The technique is used both in virtualization and cloud computing management, and is common in large server warehouses. 21. U ----- 22. V ----- 23. W ----- Windows 24. Z -----
xv6 is a modern reimplementation of Sixth Edition Unix in ANSI C for multiprocessor x86 systems. It is used for pedagogical purposes in MIT's Operating Systems Engineering (6.828) course.
A learning management system (LMS) is a software application for the administration, documentation, tracking, reporting and delivery of educational courses, training programs, or learning and development programs. The learning management system concept emerged directly from e-Learning. Although the first LMS appeared in the higher education sector, the majority of the LMSs today focus on the corporate market. Learning Management Systems make up the largest segment of the learning system market. The first introduction of the LMS was in the late 1990s. Learning management systems were designed to identify training and learning gaps, utilizing analytical data and reporting. LMSs are focused on online learning delivery but support a range of uses, acting as a platform for online content, including courses, both asynchronous based and synchronous based. An LMS may offer classroom management for instructor-led training or a flipped classroom, used in higher education, but not in the corporate space. LMSs can integrate with HRISs, ERPs as well as many SaaS offerings via API.
