The interaction between hardware and software is referred to as system functionality. This term encompasses the way that hardware components and software applications work together to perform tasks or processes on a computer or network. For instance, when you run an application, the CPU processes the instructions from the software, the RAM temporarily holds data required for the operation, and input/output devices like keyboards and printers facilitate user interaction.

System functionality is vital since it determines how well all system components operate together, impacting the overall performance and usability of a computer. While other terms might relate to specific aspects of the interaction, such as hardware integration or device communication, they do not capture the comprehensive relationship indicated by system functionality. System functionality thus serves as an umbrella term that reflects the seamless operation and collaboration between hardware and software in any given computing environment.
