Key Functions of an Operating System:
User Interface (UI): Provides a way for users to interact with the computer, either through a graphical user interface (GUI) or command-line interface (CLI).
Memory Management: Manages the system’s RAM and ensures that applications and processes do not interfere with each other.
Process Management: Controls the execution of processes, allocates CPU time, and ensures smooth multitasking.
File System Management: Manages how files are stored, retrieved, and organized on storage devices.
Security and Access Control: Protects the system from unauthorized access and ensures that data is secure.
Device Management: Controls and communicates with hardware devices like printers, monitors, and storage devices.
Conclusion:
Operating systems are essential software that enable devices to function. They provide the interface through which users and applications interact with the hardware and manage resources for optimal performance. Depending on the device, OS choices may vary to suit different user needs, from personal computing to specialized industrial use.
