PMS Notation
and the Question,
What is a Computer?

"PMS" refers to Processors-Memories-Switches: a computer is composed of a processor, primary memory (as opposed to secondary memory such as a disk or subcomponent memory such as registers), and a bus (or switch) that connects them (and, usually, other hardware for I/O). PMS notation is used in some textbooks to create formalized block diagrams describing how computer systems are composed of subsystems).

The following defintions are from [Bell et al. 1972, p17].
