PHB	PCI Host Bridge
physical address	A binary address that refers to the actual location of information
	stored in secondary storage.
PIB	PCI-to-ISA Bridge
PMC	PCI Mezzanine Card
POWER	Performance Optimized With Enhanced RISC architecture (IBM)
PowerPC™	The trademark used to describe the Performance Optimized With
	Enhanced RISC microprocessor architecture for Personal
	Computers developed by the IBM Corporation. PowerPC is
	superscalar, which means it can handle more than one instruction per
	clock cycle. Instructions can be sent simultaneously to three types of
	independent execution units (branch units, fixed-point units, and
	floating-point units), where they can execute concurrently, but finish
	out of order. PowerPC is used by Motorola, Inc. under license from
	IBM.
RAM	Random-Access Memory. The temporary memory that a computer
	uses to hold the instructions and data currently being worked with.
	All data in RAM is lost when the computer is turned off.
RAS	Row Address Strobe. A clock signal used in dynamic RAMs to
	control the input of the row addresses.
Raven	The PowerPC-to-PCI local bus bridge chip developed by Motorola
	for the MVME2600 and MVME3600 series of boards. It provides
	the necessary interface between the PowerPC 60x bus and the PCI
	bus, and acts as interrupt controller.
Reduced-Instruction-Set Computer (RISC)
	A computer in which the processor’s instruction set is limited to
	constant-length instructions that can usually be executed in a single
	clock cycle.
RFI	Radio Frequency Interference
ROM	Read-Only Memory
RTC	Real-Time Clock
SBC	Single Board Computer
