What is the primary role of software in a computer?

The primary role of software in a computer is to process and execute instructions. Software acts as the intermediary between the user and the hardware, enabling users to interact with the system and perform tasks. It includes operating systems, applications, and utilities that provide functionalities such as running programs, managing resources, and facilitating communication within the computer system.

When a user executes a command or opens an application, software interprets these instructions and translates them into actions that the hardware can execute. This vital function allows users to perform a wide range of operations, from simple calculations to complex computations and data management.

In contrast, the other roles mentioned do not fully capture the essence of what software does. Connecting hardware components is the responsibility of physical connectors and ports; managing the power supply pertains to hardware and power management systems, while creating user accounts, although a function performed by software, is a specific task rather than the overarching role of software in the computer system.
