An operating system (OS) is a program for executing other programs on a computer. When the user turns on the operating system automatically operates, and when the power is turned off, the operating system stops operating on the computer. This serves as the interface between the user and the CPU. The operating system controls external devices connected to the computer. External devices can manage files on your computer. The operating system can perform input from an external device such as a keyboard, printer, scanner, etc., and display its output on a computer display. This is the interface between the user and the CPU. The responsibility of the operating system is to ensure that programs and users do not interfere while running at the same time. That is why an unauthorized user does not access the system.
The operating system (OS) is the most important program that runs on a computer. Every general-purpose computer requires an operating system that runs other programs and applications. The computer operating system performs basic tasks such as recognizing input from the keyboard, sending output to the display, tracking files and directories on the storage drive, and controlling peripherals such as printers. For large scale systems, the operating system's responsibilities and capabilities will increase. It's like a traffic policeman - it guarantees that users running at the same time as different programs do not interfere with each other. The operating system is also responsible for security and prevents unauthorized users from accessing the system.
