What is the role of an operating system?

An operating system serves as the fundamental software that manages both the computer's hardware and software resources. It acts as an intermediary between the user and the computer's hardware, facilitating communication and ensuring that various programs can run efficiently without conflicts.

This includes managing the memory, processing power, disk space, and input/output devices, ensuring that each application gets the resources it needs while maintaining system stability and performance. By managing these resources, the operating system allows users to execute commands, run applications, and perform tasks smoothly and effectively.

While other choices might relate to specific functions or aspects of computing, they do not encompass the comprehensive role that an operating system plays in overall system management and operation.
