What does RISC stand for in computing?

RISC stands for Reduced Instruction Set Computing. This term refers to a computer architecture that utilizes a small set of simple instructions to execute tasks, as opposed to a more complex set of instructions that might be found in other architectures. The philosophy behind RISC architecture is that simpler instructions can be executed more rapidly and efficiently, leading to improved performance.

In RISC systems, operations are typically completed in a single clock cycle, which allows for the rapid processing of instructions. This design allows compilers to optimize code successfully by using more straightforward, streamlined commands. As a result, RISC architectures are often favored for applications where speed and efficiency are critical, such as in embedded systems and high-performance computing.

The other options present alternative terms that are not recognized in the field of computing and do not align with the established understanding of instruction sets.
