What is the function of input hardware?

Input hardware refers to devices that allow users to enter data into a computer system. This includes peripherals like keyboards, mice, scanners, and microphones, which all serve the common purpose of enabling users to provide data or commands that the computer can process. The function of input hardware is crucial as it forms the first step in the data processing cycle, allowing users to interact with computers effectively.

In contrast, the other options describe different functions: displaying data to the user pertains to output hardware like monitors and printers, storing data and software is the role of storage devices such as hard drives and SSDs, and processing commands from software is conducted by the CPU and other processing components within the computer. Thus, the choice that correctly identifies the primary role of input hardware is indeed focused on enabling users to input data.
