What function does the operating system perform?

• A. Runs applications
• B. Manages computer hardware and software resources
• C. Provides internet connectivity
• D. Protects from viruses and malware

Answer: (B)

The operating system plays a crucial role in managing the computer's hardware and software resources, which is why this answer is the most accurate. Its primary responsibilities include coordinating the use of the CPU, memory, storage devices, and input/output devices. It acts as an intermediary between users and the computer hardware, ensuring that software applications can access the necessary resources to function effectively.

By managing these resources, the operating system also handles tasks such as scheduling processes, maintaining security through access controls, and managing file systems. This comprehensive management ensures that both hardware and software can work together efficiently, making it essential for the overall operation of a computer.

While running applications, providing internet connectivity, and protecting against viruses and malware are all functions that can be associated with an operating system, they fall under the broader category of resource management. For example, running applications is a feature made possible by the operating system effectively managing the resources required by those applications.

Similarly, providing internet connectivity is a function that the operating system facilitates, but it relies on the proper management of hardware resources like network interfaces. Protection from viruses and malware is also an important aspect of an operating system's functionality, typically through security protocols and software. However, these functions are specific applications or services that stem from the
