Short for PowerPC Platform, a computer hardware specification that allows a computer to run multiple operating systems. PPCP was developed jointly by Apple, IBM, and Motorola and was first called the Common Hardware Reference Platform (CHRP). The specification is based on the RISC architecture used for the RS/6000 mini-computer.
A computer that meets the PPCP standard allows you to select an application without regard to the underlying operating system. A PPCP computer can run any Mac, PC, or UNIX-based operating system without the usual modifications required to fit an operating system to a platform.
