What does RISC stand for in computing?

RISC stands for Reduced Instruction Set Computing, which refers to a design philosophy for computer architectures. This approach focuses on simplifying the processor instruction set by including only a small number of instructions, allowing for more efficient execution of programs. The rationale behind RISC is that by streamlining the instruction set, it enables faster execution and better performance, as the CPU can execute instructions in a single clock cycle.

This design typically allows for a greater number of general-purpose registers, which can help to reduce memory access and improve overall processing speed. By using a limited set of instructions that can be executed rapidly, RISC architectures can optimize performance for various applications, especially those that require high processing capabilities, such as graphics processing and embedded systems.

The other options do not accurately reflect what RISC stands for or the principles behind this computing approach. Hence, Reduced Instruction Set Computing is the foundational concept that characterizes RISC architecture and sets it apart from other instruction set architectures.
