The difference between the organizer and the organizer:
1, different definitions: the organizer is the unit that undertakes this activity, and the organizer is the unit that specifically handles this activity.
2. The payer is different: the organizer spends money and the organizer does not spend money.
3. Different subjects: the organizer is in charge of this matter, but is unwilling or unable to do specific work, and entrusts the organizer to do it. The organizer is specifically entrusted by the organizer to handle this matter, including meeting arrangement, welcoming and sending off, venue layout, diary minutes, meeting reports, accommodation and entertainment, etc.
