Operatiivsüsteem

Operatiivsüsteem is the Estonian term for operating system. An operating system is essential software that manages computer hardware and software resources. It provides common services for computer programs. Without an operating system, a computer is just a collection of hardware components.

The primary functions of an operating system include managing the CPU, memory, storage devices, and input/output devices. It also handles process management, ensuring that multiple applications can run concurrently and efficiently. File system management is another critical role, organizing and controlling how data is stored and retrieved.

Operating systems act as an interface between the user and the computer's hardware. They provide a user-friendly environment through graphical user interfaces (GUIs) or command-line interfaces (CLIs), allowing users to interact with the computer and run applications. Examples of popular operating systems include Windows, macOS, and Linux. Mobile operating systems like Android and iOS are also widely used.

The evolution of operating systems has been driven by the need for greater efficiency, security, and user-friendliness. From early command-line systems to modern multitasking and networking capabilities, operating systems continue to be a fundamental component of all computing devices.
