What is the main role of an operating system?

• A. To provide internet access
• B. To design hardware components
• C. To manage computer resources and services
• D. To run security applications

Answer: (C)

The main role of an operating system is to manage computer resources and services. This includes overseeing the hardware components such as the CPU, RAM, hard drives, and peripheral devices, and ensuring that these resources are allocated and used efficiently. The operating system acts as an intermediary between users and the computer hardware, allowing users to execute commands and run applications without needing to understand the complex details of the hardware. In addition to resource management, the operating system handles tasks such as process scheduling, memory management, handling input and output operations, and providing a user interface. This comprehensive management is essential for the system to function smoothly and for users to have an effective computing experience. While providing internet access is a function that many operating systems support through networking capabilities, it is not their main role. Designing hardware components is outside the scope of an operating system's functions; rather, it is typically the role of hardware engineers. Running security applications may be a task performed by an operating system to help protect the computer from threats, but that is just one of many tasks the operating system performs. Therefore, managing computer resources and services encompasses the primary responsibilities of an operating system.
