Question

• A. Word processing
• B. Device Management
• C. Memory Management
• D. Process Management

Answer 1

Answer:

A. Word processing

The correct answer is Word processing.

An Operating System (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. Its core functions include:

• Memory Management: Allocating and de-allocating memory space (RAM) to programs as needed.

• Device Management: Managing input/output (I/O) devices (like keyboards, printers, and disk drives) using device drivers.

• Process Management: Handling CPU scheduling, running processes, and executing multiple tasks simultaneously.

Word processing, on the other hand, is an Application Software (e.g., Microsoft Word, LibreOffice Writer). It is designed to help users perform specific tasks like writing, editing, and formatting text documents, which runs on top of the operating system.
