RISC

   (Concise Encyclopedia)

Computer architecture that uses a limited number of instructions. RISC became popular in microprocessors in the 1980s. The traditional CISC (Complex Instruction Set Computing) architecture uses many instructions that do long, complex operations. Each RISC instruction is executed much more quickly than a CISC instruction, and most computational tasks can be processed faster. Modern instruction sets combine attributes of CISC and RISC.
