DOS is an example of an Application Program.
Correct Answer
B. False
Explanation
DOS (Disk Operating System) is not an example of an Application Program. It is an example of an operating system. An operating system is a software program that manages computer hardware and software resources and provides common services for computer programs. Application programs, on the other hand, are software programs that are designed to perform specific tasks for end-users, such as word processing, spreadsheet calculations, or graphic design.
2.
Operating System plays a vital role in the operation of the computer system.
Correct Answer
A. True
Explanation
The statement is true because an operating system is essential for managing and controlling the hardware and software resources of a computer system. It provides a user interface, manages memory and storage, schedules tasks, and ensures the proper execution of programs. Without an operating system, a computer would not be able to function properly or perform any tasks. Therefore, the operating system plays a crucial role in the operation of a computer system.
3.
Application programs require an operating system to function.
Correct Answer
A. True
Explanation
Application programs are software programs that perform specific tasks or functions, such as word processing, web browsing, or gaming. These programs rely on the underlying operating system to provide essential services and resources, such as memory management, file access, and hardware interaction. Without an operating system, application programs would not have access to these necessary functions and would not be able to run properly. Therefore, it is true that application programs require an operating system to function.
