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.
