Tables that exist in the base system are called core tables.These are created by ServiceNow and provided with the base system. Custom tables are created by you (users).

To understand the list of core tables, one should understand concept of base, parent and child classes. 

A table that exists another table is called a child class and the table it extends is called a parent class. 

Examples: 

1. Task[task] table  -> Child tables are Change Request, Incident and Problem tables

2. Configuration Item [cmdb_ci] -> Database, Hardware and Software tables

If a table is extended but itself is not extending another table is called Base class/table

Example:

The Task[task] table is such a table, making it both the base class (not extending another table), and a parent class (extended)
