Käyttöjärjestelmämallinnus

Käyttöjärjestelmä is the Finnish word for operating system. An operating system is the foundational software that manages computer hardware and software resources and provides common services for computer programs. It acts as an intermediary between the user and the computer's hardware. Key functions of an operating system include process management, memory management, file system management, and device management.

Process management involves allocating processor time to various running applications. Memory management ensures that each process has enough memory to run and prevents them from interfering with each other. File system management organizes data on storage devices, allowing users and applications to access files and directories. Device management handles input and output operations, communicating with hardware devices like printers and keyboards.

Popular examples of operating systems include Windows, macOS, and Linux for personal computers, and Android and iOS for mobile devices. Each operating system has its own user interface, set of features, and compatibility with different hardware and software. The choice of an operating system often depends on the user's needs, preferences, and the intended use of the computer. The development of operating systems has been crucial for the evolution of computing, making computers more accessible and powerful for a wide range of users.
