📚 Topic Summary
Operating systems (OS) are the unsung heroes of our digital world. They manage the computer's hardware and software resources, allowing multiple programs to run seemingly simultaneously. This is achieved through process management, where the OS creates, schedules, and terminates processes (running programs). Understanding these processes is fundamental to grasping how computers function. This unplugged activity will simulate these processes using simple materials and teamwork, making it easy to visualize complex computer science concepts.
