osasüsteem

osasüsteem is a term that translates from Estonian to "operating system." In the context of computing, an operating system is the fundamental software that manages a computer's hardware and software resources. It acts as an intermediary between the user and the computer's hardware, providing a platform for applications to run. Without an operating system, a computer would be unable to perform basic functions like booting up, running programs, or interacting with peripherals such as keyboards and monitors.

The primary functions of an operating system include process management, memory management, file system management, and device management. Process management involves controlling the execution of programs, allocating CPU time, and handling communication between different processes. Memory management ensures that each process has enough memory to run and prevents them from interfering with each other. File system management organizes and stores data on storage devices, allowing users to create, delete, and access files and directories. Device management handles the interaction with hardware devices, such as printers, network cards, and storage drives, through device drivers.

Common examples of operating systems include Microsoft Windows, macOS, Linux, Android, and iOS. Each operating system has its own unique interface, features, and underlying architecture, catering to different user needs and hardware platforms. The choice of operating system can significantly impact a user's experience and the types of software they can utilize.
