In addition to what Devzee wrote:
TYPE=TP PCB's are for communicating with the message-queue which you may also consider some kind of database. As you may know every database, including the message-queue, needs a PCB for program communication with that particular database. The TP-PCB is usually called an IO-PCB and is responsible for communication of message sent to and from a terminal. You may also define an alternate-pcb (MODIFY=YES)which may be used to route messages to a different terminal or other MPP's.
Since BMP's also may process messages they also use an IO-PCB.
