Final answer:

Step-by-step explanation:
A colleague excitedly tells you she has created an interface component for SPSS, a statistics software program. She has created a plugin or add-on.
When we talk about something created or modified by humans for a practical purpose, particularly in the context of software, we generally refer to it as a component. This is a distinct part or element of a larger system. In the case of SPSS, which is a comprehensive statistical analysis software suite, adding a component typically means enhancing its functionality with a specific feature or tool, aiming to simplify or extend the capabilities of the software.
