Operating Systems: Process Management and Memory Allocation

Understanding how an operating system manages hardware resources is essential for writing efficient, high-performance software. This text-based course guides you through the inner workings of operating systems, demystifying how processes execute, communicate, and share memory. By the end of this course, you will transition from simply writing code to understanding how the underlying platform schedules, runs, and protects your applications, preparing you for technical interviews, academic exams, or system-level development. What you'll learn: - Understand core operating system definitions, structures, and system call mechanisms. - Analyze CPU scheduling algorithms to determine how processes share processor time. - Solve process synchronization challenges using semaphores, mutexes, and classic concurrency patterns. - Master memory management techniques including paging, segmentation, and virtual memory. - Explore modern virtualization concepts and how container engines interact with the host OS kernel. - Practice solving typical technical evaluation problems related to deadlock detection and avoidance. We begin with foundational definitions of processes and threads before moving systematically through synchronization, memory allocation, and storage management. You will read detailed explanations and analyze pseudocode examples that illustrate how modern kernels handle complex multitasking. Designed for computer science students, self-taught developers, and software engineers looking to solidify their systems programming foundations, this course starts with the absolute basics and requires no prior kernel development experience.
