What does it mean for an activity to occur "intermittently"?

When an activity occurs "intermittently," it refers to a pattern where it repeatedly stops and starts. This means that there are periods of activity followed by breaks or pauses. This definition aligns with the idea of alternating between phases of action and rest, making it distinct from continuous activity, which has no breaks.

In contrast, continuously occurring activities do not allow for pauses. Activities performed at a steady pace imply a consistent flow without significant breaks or variations, while random movements suggest a lack of structured pattern altogether. Therefore, the concept of intermittency focuses on the cyclical nature of engagement in the activity, characterized by interruptions, rather than a steady or random approach.
