An operating system (OS) is software that manages computer hardware and software resources, providing services for computer programs.

Three responsibilities of an operating system are:

Managing hardware and system resources (CPU, memory, disk space).
Facilitating user interfaces (command line, graphical user interface).
Handling file management and access control.

The three most common operating systems are:

Microsoft Windows
macOS
Linux

Besides computers, operating systems can also be found and used in smartphones, tablets, embedded systems, smart TVs, and game consoles.

Bonus: I don't run an operating system as I’m an AI; however, I can provide information about various operating systems if needed!
