Step-by-step explanation:
The subject described in the question is Operating Systems. An operating system is a software that controls and coordinates the use of hardware among various applications and users. It manages the resources of a computer system, including the allocation of memory, processing power, and input/output devices.
Operating systems play a crucial role in facilitating human software interactions in complex automated systems. They provide an interface for users to interact with the computer and make decisions. For example, when a user opens a word processing application or solves an equation on their computer, the operating system manages the execution of these tasks.
Some examples of operating systems include Microsoft Windows, MacOS, and Linux. Each operating system has its own set of features and functionalities, but their main goal is to ensure efficient and reliable use of computer hardware.
