What is the difference between system objects and user objects?

Question

Explain the difference between system objects and user objects

Answer 1

 SQL Server creates system objects during the installation process.
 They are part of the system, and most of them are necessary for SQL Server to function properly.
 Whereas system objects are part of the SQL Server system, you create user objects.
 User objects include the databases, stored procedures, functions, and other system objects that you build.
