Good morning Jasur how are you? I am fine thank you.

Jasur, tell me about operating systems.

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

I see, Jasur. Who invented operating system?

The first operating system was created by General Motors in 1956 to run a single IBM mainframe computer.

Thank you, Jasur. What are the 4 main operating systems?

A computer has four general types of memory. In order of speed, they are: high-speed cache, main memory, secondary memory, and disk storage.

Jasur , please give examples?

Some examples include versions of Microsoft Windows (like Windows 10, Windows 8, Windows 7, Windows Vista, and Windows XP), Apple's macOS (formerly OS X), Chrome OS, BlackBerry Tablet OS.
