Step-by-step explanation:
The operating system's interactions are primarily with the human software interactions in complex automated systems, especially the decision-making processes of workers as they are supported by the software system.
In other words, the operating system acts as an interface between the hardware of a computer and the software applications that run on it. It manages resources, such as memory and processing power, and facilitates communication between different components of the system.
