Question textCompare the two architectures (Von Neumann and Harvard) by selecting the correct characteristics for each aspect. (8 marks) 1. Memory Organization In the Von Neumann architecture, data and instructions are stored in a: Answer 1 Question 33[select: , Single shared memory for both data and instructions, Separate memory for data only, Separate memory for instructions only, Independent caches] In the Harvard architecture, data and instructions are stored in: Answer 2 Question 33[select: , Separate memories for data and instructions, One shared memory, Virtual memory only, Secondary storage] 2. Bus ConfigurationVon Neumann architecture uses: Answer 3 Question 33[select: , A single bus for both data and instructions (bottleneck), Two independent buses, A wireless bus, A segmented bus system] Harvard architecture uses: Answer 4 Question 33[select: , Separate instruction and data buses, One shared bus, An external bus only, A cached instruction bus only] 3. Instruction/Data FlowInstruction and data in Von Neumann architecture travel through: Answer 5 Question 33[select: , The same pathway, Separate pipelines, Dedicated execution buffers, Read-only bus] Instruction and data in Harvard architecture travel through: Answer 6 Question 33[select: , Independent pathways, Shared execution lanes, Cache-only paths, Virtual routing] 4. Execution Efficiency Von Neumann architecture is generally: Answer 7 Question 33[select: , Slower due to the bottleneck, Faster due to dual buses, More efficient in parallel tasks, Only used in GPUs] Harvard architecture is generally: Answer 8 Question 33[select: , Faster due to parallel access, Slower due to single bus, Less efficient with branching, Dependent on virtual memory]

Step-by-Step Analysis
Question 33 asks you to compare Von Neumann and Harvard architectures across four aspects and select the correct statements for each part. Below, I break down each sub-question and evaluate every option to help you reason through the correct choices. 1. Memory Organization - Von Neumann architecture options: • Single shared memory for both data and instructions • Separate memory for data only • Separate memory for instructions only • Independent caches Explanation: In the classic Von Neumann design, there is a single, unified memory that holds both instructions and data. This shared memory is what leads to the potential bottleneck when the CPU tries to fetch instructions and data simultaneously. - Harvard architecture options: • Separate memories for data and instructions • One shared memory • Virtual memory only • Secondary storage Explanation: Harvard architecture uses distinct memories for instructions and for data, allowing parallel access to bo......Login to view full explanation
