RISC (Reduced-Instruction Set Computing) - Definition

RISC is an abbreviation for Reduced Instruction Set Computing. It is a CPU design that requires the processor to handle very simple instructions. This enables the processor to execute these instructions at a very high speed. Motorola's PowerPC processors, used on both Mac and PC platforms, use RISC design. The idea was originally inspired by the discovery that many of the features that were included in traditional CPU designs to facilitate coding were being ignored by the programs that were running on them.
