A unit that performs a complete portion of a larger task and consists of one or more subprograms is referred to as what?

A unit that performs a complete portion of a larger task and consists of one or more subprograms is referred to as a module. In software engineering, a module is a self-contained piece of software that contributes to a larger application. It encapsulates specific functionality and can include multiple subprograms, functions, or procedures that are designed to work together to accomplish a particular aspect of the overall system's functionality.

Modules help in organizing code, promoting reusability, and enhancing maintainability. By breaking down a system into smaller, manageable modules, developers can focus on individual components, making the code easier to understand and debug. This modular approach encourages a clean separation of concerns, facilitating collaboration among team members who may work on different modules concurrently.

While the other options like library, component, and class have their own specific meanings and uses within software development, they do not fully capture the definition of a unit dedicated to completing a portion of a larger task in the way that a module does. Libraries are collections of pre-written code intended for reuse, components refer to independent parts that make up a system but may not always consist of subprograms, and classes are constructs used in object-oriented programming to define objects but do not specifically convey the broad functionality aspect of
