Von Neumann Architecture Quiz

What is the primary purpose of the CPU in the von Neumann architecture?

• To store data permanently

• To execute instructions

• To connect input and output devices

• To manage software applications

What does RAM stand for?

• Random Access Memory

• Read Access Memory

• Rapid Application Module

• Readily Available Memory

What role does the program counter play in the fetch-decode-execute cycle?

• It decodes the instruction

• It holds the address of the next instruction

• It stores data temporarily

• It performs calculations

What is the function of the control unit within the CPU?

• To perform arithmetic operations

• To decode instructions and control data flow

• To store instructions

• To manage the clock speed

Which bus is responsible for carrying data to and from the CPU?

• Address bus

• Data bus

• Control bus

• Instruction bus

What is the primary function of the clock in the von Neumann architecture?

• To synchronize operations in the CPU

• To store instructions

• To increase RAM speed

• To manage peripheral devices

What is stored in the registers of the CPU?

• All instructions for the program

• Frequently used data and instructions

• Data for permanent storage

• Output data only

Which component performs arithmetic and logic operations in the CPU?

• Control unit

• Arithmetic Logic Unit (ALU)

• Register

• Address bus

What does the address bus do during the fetch stage?

• Transfers data to the CPU

• Carries the memory address to RAM

• Synchronizes the clock

• Decodes the instruction

What happens during the decode stage of the fetch-decode-execute cycle?

• The CPU fetches the instruction from RAM

• The instruction is interpreted by the control unit

• Data is stored in registers

• Results are sent to output devices
