Within a computer system, hardware and software interact through a defined architecture that facilitates communication. Hardware refers to the physical components, such as the CPU, RAM, and storage devices, that execute tasks. Software, on the other hand, consists of programs and applications that direct hardware operations. Operating systems serve as intermediaries, managing resource allocation and ensuring that software instructions are translated into hardware actions. This interaction allows users to perform various tasks, from document editing to gaming, highlighting the essential relationship between hardware capabilities and software functionalities.
