Which type of software is an operating system categorized as?

An operating system is categorized as system software because it serves as the fundamental interface between the computer's hardware and the application software that runs on it. System software manages and coordinates the hardware components of the computer while also providing a platform for applications to operate. This category includes not only operating systems but also device drivers and other essential programs that manage system resources.

Application software, on the other hand, refers to programs that perform specific tasks for users, such as word processors, spreadsheets, and database management systems. Utility software is a subtype of system software designed for maintenance tasks, such as disk cleanup tools and antivirus software. Firmware represents a specialized type of software that is closely tied to hardware and provides low-level control, typically residing in the hardware itself.

Understanding this distinction clarifies the role an operating system plays and why it is classified as system software rather than falling into the other categories.
