RISC
Reduced Instruction Set Computer. This is a design of microprocessor that basically performs a subset of the most important functions very quickly indeed. Complex tasks have to be broken down into tasks in the subset.

RISC
Reduced Instruction Set Computing chipsets such as the MIPS R4000 and R4400 intended to outperform CISC complex instruction chipsets such as the Intel family of popular 386, 486, and Pentium competitors and the Motorola 680x0 family in Mac computers. The concept of RISC evolved from IBM laboratories where it was noted that most routine processing of consumers does not require full use of the processor. RISC processors consume less power and generate less heat than CISC processors powerful enough to compete at the same speed and capacity as RISC processors. They do this by reducing the number of operations and executing multiple instructions in what is known as "superscaler" processing. However, INTEL intends to keep its CISC lines competitive with RISC processors. At this juncture, it is impossible to know who will win the RISC versus CISC processor competitions of the future. The RISC-architecture is the foundation of the new PowerPCs and the PA-RISC systems of Hewlett-Packard Corporation. The HP 32-bit PA-7100 chip, for example, runs about 25% faster than the PowerPC RISC chips and the Pentium CISC chips. A new RISC processor from Texas Instruments called the Multimedia Video Processor is claimed to be 20 to 50 times more powerful than Intel's Pentium. RISC chipsets may become more of a threat to CISC in the form of NexGen alternatives to Pentium that are being manufactured by Alaris for Compaq, IBM, and other major PC manufacturers.

RISC
Stands for "Reduced Instruction Set Computing," pronounced like "risk." It is arguably the fastest and most effiecient microprocessor technology available today. The RISC architechture is an improvement upon the CISC (Complex Instruction Set Computing) architecture used in most Pentium chips. In 1974, John Cocke of IBM Research worked to make an even faster version of the CISC chip, and came up with a result that majorly reduced the number of instructions the chip needed to perform. The new technology was not only faster than CISC chips, but the chips were also easier and less expensive to manufacture. Motorola's PowerPC chips (such as the G4 in Power Macs) are the most widely used RISC-based chips. Intel has slowly been integrating RISC technology into its chips, but they still are mostly CISC-based, which causes the chips to suffer in floating-point calculations.

Reduced instruction set computer
The reduced instruction set computer (RISC, pronounced like "risk") is a CPU design philosophy that favors an instruction set reduced both in size and complexity of addressing modes, in order to enable easier implementation, greater instruction level parallelism, and more efficient compilers. As of 2007, common RISC microprocessors families include the DEC Alpha, ARC, ARM, AVR, MIPS, PA-RISC, Power Architecture (including PowerPC), and SPARC. 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. Also these more complex features took several processor cycles to be performed. Additionally, the performance gap between the processor and main memory was increasing. This led to a number of techniques to streamline processing within the CPU, while at the same time attempting to reduce the total number of memory accesses.
