Is AS400 difficult to learn?
Most of us learn through more practice and less theory. By that method of learning, learning IBMi (AS400) Administration can be little more challenging than learning to build application or programming in i. You can get a public IBMi server for practice programming but you may not get one for actual administration.

How does a mainframe work?
Mainframes process large amounts of small data rapidly using CPUs, SAPs and I/Os: When a request for information is filled (i.e. a flight attendant searching a reservation) it gets sent to a mainframe. The main CPU sends the request to additional processors (SAPs) to move data to the correct I/O processor cards.
