Final answer:
In OOP, functions are the mechanisms that perform tasks and are analogous to verbs; these are often called methods when associated with objects or classes.
Step-by-step explanation:
In Object-Oriented Programming (OOP), the term that describes mechanisms that perform tasks and are considered an action, or verb, are functions.
Just as verbs in a sentence describe an action, state, or occurrence, functions in OOP are used to define the behavior of objects. They can perform calculations, manipulate data, or execute any task. Functions are attached to objects as methods, providing them the ability to act and respond to other objects and data within the program.
In the context of OOP, methods are a specific type of function that are associated with an object or class, which solidifies the connection between functions as actions (verbs) and their role in object-oriented design.
