Which term refers to the core software that runs hardware and provides services to other programs?

• A. Loop
• B. Integer
• C. Operating System (OS)
• D. Data

Answer: (C)

The key idea is that the operating system is the software layer that runs the hardware and provides services to other programs. It manages the computer’s resources—CPU time, memory, and devices like disks and keyboards—and offers core services such as process management, file systems, and input/output handling. Applications interact with the OS through standardized interfaces, which lets them run on different hardware without needing to know the specifics of the underlying components. Other terms don’t fit this role. A loop is a programming construct used to repeat actions, an integer is a numeric data type, and data refers to information stored or transmitted. None of these describe the essential software layer that coordinates hardware and supplies services to programs.
