What is a mainframe trainer?

Mainframe Trainers are professionals who specialize in teaching individuals or groups how to use and manage mainframe computer systems, which are powerful computers used primarily by large organizations for critical applications. They design and deliver training programs on mainframe technologies such as COBOL, JCL, DB2, and system administration.
