What is the relationship between the terms "job", "task", and "step"?

edit

A job is a set of tasks or activities performed to achieve a specific objective or complete a particular role or position. Tasks are a set of actions or activities that are part of a job or project that must be completed to reach its objective. Steps are the individual actions or movements taken to complete the tasks involved in a job or project. In short, tasks are made up of steps, and jobs are made up of tasks.
