Please read the guide .
Please answer the question in detail
The three main purposes of an operating system (OS) are:
Convenience: An operating system should be convenient for users to interact with and use. It should provide a user-friendly interface that is easy to navigate and use, and it should offer features that make common tasks easier to perform. A convenient operating system should also provide tools for managing files, settings, and other system resources in a way that is intuitive and efficient.
Efficiency: An operating system should be efficient in its use of system resources. It should allocate resources to running programs in a way that maximizes the system's performance and ensures that programs run smoothly. An efficient operating system should also minimize system overhead, such as CPU and memory usage, to reduce the system's overall resource consumption.
Ability to evolve: An operating system should be able to evolve over time to meet the changing needs of users and the computing environment. This means that the operating system should be designed to support new hardware and software technologies as they emerge, and it should be flexible enough to adapt to new use cases and user requirements. An operating system that can evolve also means that it can be updated to address security vulnerabilities and other issues that arise over time.
