The questions ask List four major functions of an OS.
My answer:
Function 1: Provide a user interface
Function 2: Manage files
Function 3: Manage hardware
Function 4: Manage applications
Is my answer correct?
Yes, your answer is correct. An operating system (OS) performs several functions to maintain and control the overall functioning of a computer system. Here are four major functions of an OS:
Function 1: Provide a user interface - The OS is responsible for providing an interface through which users can interact with the computer system. This interface can be in the form of a graphical user interface (GUI) or a command-line interface (CLI).
Function 2: Manage files - The OS handles the organization, storage, and retrieval of files on the computer's storage devices. It provides the necessary file management system, allowing users to create, delete, modify, and access files efficiently.
Function 3: Manage hardware - The OS interacts with and manages various hardware components of the computer system. It provides device drivers that enable communication between software applications and hardware devices, allowing programs to utilize hardware resources effectively.
Function 4: Manage applications - The OS facilitates the execution and management of software applications on the computer system. It provides a runtime environment where applications can run, manages system resources to allocate them to different processes, and ensures that applications operate within their allocated boundaries.
To arrive at these functions, you can analyze the core responsibilities traditionally associated with operating systems and the tasks they perform. Additionally, studying introductory textbooks or online resources on operating systems can provide you with a comprehensive understanding of their functions.
