The correct option for the question "A major function of system software is___?" is C. File management. Detailed Explanation 1. Understanding System Software: System software is a type of software designed to provide a platform for other software. It includes operating systems (like Windows, macOS, Linux), device drivers, and utility programs. The primary role of system software is to manage hardware and software resources on a computer. 2. Major Functions of System Software: Among the various functions of system software, file management is one of the most critical. File management involves the organization, storage, retrieval, naming, sharing, and protection of files on a computer system. This function is essential for users to efficiently access and manage their data. 3. Why Option C is Correct: - File Management: System software provides the necessary tools and interfaces for users to create, delete, move, copy, and organize files. It manages the file system, which is the way data is stored and organized on storage devices. This includes maintaining the directory structure, handling file permissions, and ensuring data integrity. - User Interaction: Through the operating system, users can interact with files using graphical user interfaces (GUIs) or command-line interfaces (CLIs), making it easier to manage their data. Why the Other Options are Incorrect: A. Collection of Files: - This option is vague and does not accurately describe a function of system software. While system software does involve managing collections of files, simply stating "collection of files" does not encompass the broader and more complex functions of file management, such as organization, retrieval, and security. B. Translation of machine language into machine code: - This option is misleading. Machine language and machine code are often used interchangeably, as machine code is the binary representation of machine language instructions. System software does not translate machine language into machine code; rather, it executes machine code directly. The translation typically refers to the role of compilers and interpreters, which are part of application software, not system software. D. Arrangement of files in ascending order: - While arranging files in a specific order (like ascending or descending) can be a part of file management, it is a very narrow function. File management encompasses much more than just sorting files; it includes creating, deleting, moving, and securing files, as well as managing the overall file system structure. Summary of Key Points:

• System software is essential for managing hardware and software resources.
• A major function of system software is file management, which includes organizing, storing, and retrieving files.
• Other options either misrepresent the functions of system software or are too narrow in scope.
• Understanding the role of system software helps in grasping how computers operate and manage data effectively.

This thorough understanding of system software and its functions will aid in your preparation for professional exams in computer science.
