🧠 Explanation:
The operating system (OS) is the most common type of system software, which manages computer hardware, software resources, and provides services for application programs. The term “system software” is a noun phrase, where “system” describes the software category and “software” identifies it as a program. Examples include Windows, Linux, and macOS. Unlike application software, which performs specific user tasks, system software acts as a bridge between hardware and user applications, ensuring smooth operation of the computer. Alternatives in context could be platform software or core software, but “system software” is the standard term. Understanding this distinction is crucial for PPSC computer literacy questions.
