Difference Between 'Active users' and 'Registered users'

Actual difference between 'Active Users' and 'Registered Users'

What is the difference between "Active users" and "Registered users"?

• An "Active user" is any user in your LMS who can sign in concurrently. For example, "25 active users" means that only 25 users can log in to your LMS instance at the same time. Logged-in users who are idle for an hour will be logged out and removed from the active users count. You can also manually log off users in the 'People' --> 'Users' page under user options.
• A "Registered user" is any user who has a user account in your LMS instance. You can have unlimited registered users created.
