Which type of computing mainly emphasizes simpler instructions?

The correct answer, which emphasizes simpler instructions, is RISC, or Reduced Instruction Set Computer. RISC architecture focuses on a smaller set of instructions, each designed to execute in a single clock cycle. This design principle enhances performance by allowing the hardware to optimize and execute instructions more efficiently. The simplicity of RISC instructions enables greater speed and lower power consumption, making it particularly effective for applications that require high performance with minimal resource use.

In contrast, CISC (Complex Instruction Set Computer) architecture contains a larger set of instructions, including complex operations, which can result in more cycles to execute these instructions. This can lead to increased design complexity and potentially slower performance in specific contexts. VLIW (Very Long Instruction Word) architecture utilizes multiple concurrent operations but does not inherently focus on simpler instructions and is more aimed at instruction-level parallelism. Quantum computing, while advancing rapidly, is fundamentally different and not directly comparable to these instruction set architectures as it relies on quantum bits and quantum states rather than traditional instruction execution.
