Operating Systems

An operating system (OS) is a software that manages computer hardware and software resources while providing common services for computer programs. It acts as an intermediary between the user and the computer hardware, allowing users to interact with the computer and execute tasks efficiently.

There are different types of operating systems, including Windows, macOS, Linux, Unix, and Android, each with its unique features and functionalities. An operating system provides various essential functions, such as managing memory, handling input and output devices, facilitating file management, and ensuring security.

The primary roles of an OS include:

• Process management: Control and allocate system resources to different tasks.
• Memory management: Handle memory allocation and deallocation for efficient multitasking.
• File system management: Organize and manage files, directories, and storage devices.
• User interface: Provide a means for users to interact with the computer system.
• Device management: Handle input/output devices, such as printers, keyboards, and mice.

Overall, an operating system plays a crucial role in keeping the computer system running smoothly, managing resources, and making it more user-friendly and efficient.
