RISC stands for which term?

• A. Read-only Memory
• B. Registered Jack
• C. Reduced Instruction Set Computer
• D. Random-access Memory

Answer: (C)

RISC stands for Reduced Instruction Set Computer—the acronym expansion is what this item tests. This design approach favors a small, simple set of instructions that are easy to decode and execute quickly, typically in a single clock cycle. That simplicity makes it easier to pipeline instructions and maintain high throughput, since each operation is uniform and straightforward for the processor to handle. It contrasts with more complex instruction sets that try to do more in one instruction but require more complex decoding.

The other terms refer to completely different concepts: Read-only Memory is a non-volatile storage used for firmware; Registered Jack is a telecom connector standard; Random-access Memory is volatile memory used for active data and programs during operation.
