Which of the following describes the role of software?

Software plays a critical role in enabling users to interact with hardware. It serves as an intermediary that translates user commands into a language that hardware can understand and execute. For instance, when a user inputs a command or interacts with an application, the software interprets this input and utilizes the hardware resources, such as the processor and memory, to perform the desired actions.

This interaction is essential because hardware on its own cannot function effectively without software to direct it. Software provides the necessary instructions for the hardware components to work together in performing tasks and processes that fulfill user needs, such as running applications, managing files, or connecting to the internet.

The other options address different aspects of computing but do not accurately describe the role of software. While physical structure and connections between devices are significant in computing, these are typically managed by hardware rather than software. Moreover, converting binary code to decimal is a specific function within computing processes, but not a generalized role of software. Thus, the correct answer highlights the essential function of software in facilitating user interaction with hardware systems.
