Question

The Sun Microsystems processors usually follow ________ architecture.

• A. CISC
• B. RISC
• C. ISA
• D. SPARC

Hint:

- Sun Microsystems processors are based on RISC architecture.
- SPARC (Scalable Processor Architecture) is a RISC-based architecture developed by Sun Microsystems.
- RISC processors use simple and fast instructions, making them efficient for high-performance computing.

Answer 1

The Correct Option is B

Step 1: Understanding Sun Microsystems Processors
- Sun Microsystems was a key developer of high-performance computing systems.
- Their processors were based on the RISC (Reduced Instruction Set Computing) architecture.
- RISC processors execute simpler instructions that enable faster performance compared to CISC (Complex Instruction Set Computing) architecture.
Step 2: SPARC (Scalable Processor Architecture)
- Sun Microsystems developed the SPARC (Scalable Processor Architecture) as a RISC-based processor architecture.
- SPARC itself is a type of RISC architecture, making RISC the correct answer.
Step 3: Evaluating the Options
- (A) Incorrect: CISC (Complex Instruction Set Computing) is not used by Sun Microsystems; it is typically used by Intel x86 processors.
- (B) Correct: Sun Microsystems processors follow the RISC architecture.
- (C) Incorrect: ISA (Instruction Set Architecture) is a general term that does not specify Sun Microsystems' architecture.
- (D) Incorrect: SPARC is an implementation of RISC, but RISC is the broader architecture.
