From a programmer’s viewpoint, processes can be in three states—running (or ready), suspended (e.g., waiting for signals like SIGCONT after sleep or wait), and terminated (after exit or Ctrl+C), with explanations of how signals control transitions and what each state signifies.
This article explains the fundamental concepts of operating systems, describing how the CPU functions as a factory, the distinction between static programs and dynamic processes, the role of threads, and synchronization mechanisms such as mutexes, semaphores, and inter‑process communication.
