The term that refers to the software enabling communication between hardware and software on a computer is the operating system. An operating system (OS) acts as an intermediary layer, managing hardware resources such as CPU, memory, and storage, and providing services to application software. It facilitates user interaction with the computer and coordinates all peripheral operations, ensuring that applications run smoothly and efficiently.

While firmware, application software, and utility software play significant roles in computing, they do not serve the same fundamental function as the operating system. Firmware refers to low-level software programmed directly into hardware devices, providing control over hardware functionalities but not serving as a general communication layer. Application software includes programs designed to perform specific tasks for users, but it relies on the operating system to function. Utility software enhances or manages the operating system by performing maintenance tasks but does not itself manage hardware and software communication at the level of the operating system.
