What was common and what was the difference between orders and collegia?

The number of Orders was greater than the number of Colleges. Orders formed in a natural way, there was no subordination between them, certain functions were assigned to them. The decision under the Order system was made alone (there was a responsible person). The collegiums were created artificially under Peter 1. These were government bodies that were subordinate to the Senate, that is, there was a vertical of power. Management was carried out centrally.
