1. Which are the processors based on RISC?
a) SPARC
b) 80386
c) MC68030
d) MC68020
Explanation: SPARC and MIPS processors are the first generation processors of RISC architecture.
2. What is 80/20 rule?
a) 80% instruction is generated and 20% instruction is executed
b) 80% instruction is executed and 20% instruction is generated
c) 80% instruction is executed and 20% instruction is not executed
d) 80% instruction is generated and 20% instructions are not generated
Explanation: 80% of instructions are generated and only 20% of the instruction set is executed that is, by simplifying the instructions, the performance of the processor can be increased which lead to the formation of RISC that is reduced instruction set computing.
3. Which of the architecture is more complex?
a) SPARC
b) MC68030
c) MC68020
d) 8086
Explanation: SPARC is more complex.
4. Which is the first company who defined RISC architecture?
a) Intel
b) IBM
c) Motorola
d) MIPS
Explanation: In 1970s IBM identified RISC architecture.
5. Which of the following processors execute its instruction in a single cycle?
a) 8086
b) 8088
c) 8087
d) MIPS R2000
Explanation: MIPS R2000 possess RISC architecture in which the processor executes its instruction in a single clock cycle and also synthesize complex operations from the same reduced instruction set.
6. How is memory accessed in RISC architecture?
a) load and store instruction
b) opcode instruction
c) memory instruction
d) bus instruction
Explanation: The data of memory address is loaded into a register and manipulated, its contents are written out to the main memory.
7. What is CAM stands for?
a) computing addressable memory
b) complex addressable memory
c) content-addressable memory
d) concurrently addressable memory
Explanation: Non-von Neumann architecture is based on content-addressable memory.

a) TEXAS TMS320
b) 80386
c) 80286
d) 8086
Explanation: It is a digital signal processor which have small and highly optimized audio or video processing signals. It possesses multiple parallel data bus.
9. Which company further developed the study of RISC architecture?
a) Intel
b) Motorola
c) university of Berkeley
d) MIPS
Explanation: The University of Berkeley and Stanford university provides the basic architecture model of RISC.
10. Princeton architecture is also known as
a) von Neumann architecture
b) Harvard
c) RISC
d) CISC
Explanation: The von Neumann architecture is also known as von Neumann model or Princeton architecture.
