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 34[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 34[select: , Separate memories for data and instructions, One shared memory, Virtual memory only, Secondary storage] 2. Bus ConfigurationVon Neumann architecture uses: Answer 3 Question 34[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 34[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 34[select: , The same pathway, Separate pipelines, Dedicated execution buffers, Read-only bus] Instruction and data in Harvard architecture travel through: Answer 6 Question 34[select: , Independent pathways, Shared execution lanes, Cache-only paths, Virtual routing] 4. Execution Efficiency Von Neumann architecture is generally: Answer 7 Question 34[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 34[select: , Faster due to parallel access, Slower due to single bus, Less efficient with branching, Dependent on virtual memory]

Step-by-Step Analysis
Here’s a step-by-step analysis of each aspect and option presented. 1. Memory Organization - Option: 'Single shared memory for both data and instructions' — This is the hallmark of the Von Neumann architecture, which uses one memory space for both data and instructions, leading to potential contention. This option is correct for Von Neumann and contrasts with Harvard's separate memories. - Option: 'Separate memories for data and instructions' — This is characteristic of the Harvard architecture, not Von Neumann. It’s incorrect when describing Von Neumann, though it would be true for Harvard. - Option: 'Separate memory for data only' — This describes a system that does not fit the standard Von Neumann model; it’s not accurate for Von Neumann and thus incorrect. - Option: 'Separate memory for instructions only' — Similarly, this would not describe Von Neumann; it’s an inaccurate portrayal for the given question. 2. Bus Configuration - Option: 'A single bus for both data......Login to view full explanation
