An operating system (OS) is the core software that powers your computer, smartphone, tablet, or any other computing device. It acts as the bridge between you and the complex hardware, providing a user-friendly interface and managing essential tasks like running applications, allocating resources, and ensuring your device functions smoothly. Think of it as the conductor of a digital orchestra, orchestrating the various components to work in harmony.pen_spark
