Step-by-Step Analysis
In approaching this question about RISC architecture, I’ll evaluate each option to see how well it matches the defining traits of RISC.
Option a: 'Complex multi-step instructions' — This actually describes CISC (Complex Instruction Set Computing) more than RISC. RISC aims to keep instructions simple and ......Login to view full explanationLog in for full answers
