Final answer:
Periodic mode is the data processing mode with delays between steps, occurring at regular intervals, often measured in milliseconds.
Step-by-step explanation:
The processing mode in which there is a delay between the various data processing steps is referred to as periodic mode. In this context, periodic mode means that processing occurs at regular intervals, rather than continuously or in real time. This can be likened to how a period in other contexts refers to a consistent interval of time between events, with time often being measured in convenient units such as milliseconds (ms). In periodic mode, each step of the processing is executed at a specific interval or time period. This delay allows for synchronization and coordination of the data processing.
