🧠 Explanation:
A computer cannot boot without an operating system, which manages hardware and software interactions. Stored on the hard drive, it initializes components during startup, enabling functionality. Without it, the system remains non-operational, highlighting its critical role. Understanding the operating system’s function is key in computer science, affecting troubleshooting and system design. This concept underscores the importance of software in modern technology, ensuring devices operate smoothly in personal, professional, or industrial applications, a foundational topic in IT studies.
