π‘οΈ Runs Programs: Apps like Microsoft Word, Chrome, and games run on top of the OS
π Manages Files: Helps you open, save, delete, and organize your files
π Connects to Networks: Allows your device to connect to Wi-Fi, Bluetooth, and the internet
π Manages Memory & Power: Controls how much memory each app uses and helps save battery life on laptops and phones
