What is the primary function of software?

The primary function of software is to provide digital instructions and programs for computers. Software serves as the intermediary between the user and the hardware, translating user commands into a format that the hardware can execute. It encompasses various types, including operating systems, applications, and utilities, all of which perform specific tasks that enable users to utilize computers effectively. Without software, hardware would remain largely inoperative, as it requires programming to perform useful functions, manage resources, and facilitate user interactions.

While the other options might relate to aspects of computing, they do not encapsulate the core purpose of software. For instance, maintaining physical systems pertains more to hardware management rather than the software's function. Creating network connections is a function of networking software but does not capture the broader role of software in computing. Enhancing user interfaces involves software as well, but it’s just one of many functionalities software provides, rather than its primary purpose.
