With recall questions, you have to remember something or something has to be recalled. Example: A teacher asks his students a question so that they remember the material from the last lesson.
Process questions are similar to recall questions but they need some deeper thoughts and maybe also analysis.
In live online training, it is sometimes useful to divide the students into small groups for certain exercises, as it would be impossible to have conversations at the same time. Break-out-rooms are used so that people can talk to each other without disturbing the others. When the exercise is over, they are sent back to the main room.
A speech that is given without any preparation, notes, or cards, is called an impromptu speech. It is often delivered at private events (e.g., weddings or birthdays) or for training presentation skills.
