What does hardware refer to in computing?

Hardware in computing refers to the physical elements of a computing system. This includes all the tangible components that you can see and touch, such as the computer's central processing unit (CPU), memory (RAM), hard drives, monitors, keyboards, and any other peripheral devices. These components work together to perform tasks and run software applications, making the physical structure necessary for any digital operations.

Understanding this notion is crucial, as it distinguishes between hardware and software. Software refers to the programs and applications that run on the hardware, enabling users to execute tasks and interact with the system. The other options, such as data encoding processes and protocols for network communication, further highlight aspects of computing that are not related to physical components. By recognizing that hardware consists solely of physical elements, one can appreciate the role each part plays in the overarching functionality of a computing environment.
