An operating system acts as an intermediary between the user of a computer and computer hardware. The purpose of an operating system is to provide an environment in which a user can execute programs in a convenient and efficient manner.

Introduction to Systems Programming and Operating Systems
Management tasks include scheduling resource use to avoid conflicts and interference between programs. Unlike most programs, which complete a task and terminate, an operating system runs indefinitely and terminates only when the computer is turned off. One form of multiprocessing is called time-sharing , which lets many users share computer access by rapidly switching between them. This virtual memory both increases the address space available to a program and helps to prevent programs from interfering with each other, but it requires careful control by the operating system and a set of allocation tables to keep track of memory use. Perhaps the most delicate and critical task for a modern operating system is allocation of the CPU; each process is allowed to use the CPU for a limited time, which may be a fraction of a second, and then must give up control and become suspended until its next turn.
There aren't really any development fields more challenging than operating system OS development. It is the " great pinnacle of programming. Few programmers ever attempt to build an OS and many of those who do make the attempt never produce a functioning system. However, if you do make it all the way to the finish line and produce a functional operating system, you will have joined an elite group of top-flight programmers. Every program that ran on these early systems had to include all of the code necessary to run the computer, communicate with connected hardware, and perform the computation the program was actually intended to perform. This situation meant that even simple programs were complex.

This course provides a deep understanding of the operating system architecture and low-level interfaces principally, system calls and library functions that are required to build system-level, multithreaded, and network applications on Linux and UNIX systems. The course consists of a mixture of detailed presentations coupled with a large number of carefully designed practical exercises that allow participants to apply the knowledge learned in the presentations. By the completion of the course, participants will have the mastery needed to write complex system, network, and multithreaded applications on a Linux or UNIX system. Previous system programming experience on Linux, UNIX, or any other operating system is not required. The audience for this course is in practice rather diverse, and includes: Programmers developing system-level or network applications for Linux and UNIX systems, or programmers porting such applications from other operating systems e. Security engineers Site reliability engineers DevOps engineers System administrators In order to get the most out of the course, participants should have:.

Systems Programming: Designing and Developing Distributed Applications explains how the development of distributed applications depends on a foundational understanding of the relationship among operating systems, networking, distributed systems, and programming. Uniquely organized around four viewpoints process, communication, resource, and architecture , the fundamental and essential characteristics of distributed systems are explored in ways which cut across the various traditional subject area boundaries. The structures, configurations and behaviours of distributed systems are all examined, allowing readers to explore concepts from different perspectives, and to understand systems in depth, both from the component level and holistically. Professional programmers who need to learn or understand distributed application development, and undergraduate or graduate students studying distributed systems, networking, operating systems, or application development. Richard John Anthony has been a university lecturer for over 20 years with teaching focusing on operating systems, networking, distributed systems, programming and embedded systems; and he has considerable experience in curriculum design in these areas.
You will then study various memory management methods, including a chapter on allocators and how they benefit system programming. For example, most personal computers PCs have a single hard disk that stores all the files being used by the owner of the PC. Both of these applications will need exclusive access to the hard disk at various times while executing. In the case of the web browser, this might be to cache websites to disk, while in the case of the office suite, this might be to store documents.
The kernel is a computer program at the core of a computer's operating system that has complete control over everything in the system. On most systems, the kernel is one of the first programs loaded on startup after the bootloader. The critical code of the kernel is usually loaded into a separate area of memory, which is protected from access by application programs or other, less critical parts of the operating system.
