Operating System (OS) is system software that manages computer hardware and software resources and provides a platform for applications to run. It acts as an intermediary between users and hardware, handling tasks such as memory management, process scheduling, and device control.
In computing systems, the operating system is essential for running applications, managing files, and coordinating hardware components like CPU, RAM, and storage devices. It ensures efficient system performance and user interaction.
For example:
- Windows manages desktop applications, files, and hardware devices on a PC.
- Android controls mobile hardware and runs apps on smartphones.
- Linux is used to manage servers and cloud infrastructure.
- macOS provides a graphical interface and system services for Apple computers.
Common types and concepts related to operating systems include:
- Windows / Linux / macOS
- Process Management
- Memory Management
- File System
