An operating system (OS) is the software that manages computer hardware and software resources and provides common services for computer programs. It acts as an intermediary between the computer hardware and the application software running on it.
The operating system performs a variety of tasks, including managing the computer's memory, controlling input and output devices, providing file management services, managing network connections, and ensuring system security. It also provides a user interface that allows users to interact with the computer and run applications.
Some examples of popular operating systems include Microsoft Windows, macOS, Linux, Android, and iOS.
In addition to managing hardware resources, an operating system also provides several services that are essential to the functioning of a computer system. These services include:
1. Memory management: The operating system manages the allocation of memory to different programs and ensures that each program has access to the memory it needs.
2. Device management: The operating system manages the input and output devices attached to the computer, such as keyboards, mice, printers, and scanners.
3. File management: The operating system provides a file system that organizes and manages files on the computer's storage devices, such as hard drives and flash drives.
4. Security: The operating system provides security features that protect the system from unauthorized access, viruses, and other forms of malware.
5. Networking: The operating system provides networking services that allow computers to communicate with each other over a network, such as the internet.
Overall, the operating system plays a crucial role in the functioning of a computer system, enabling users to interact with their computers and run applications efficiently and securely.
