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 10[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 10[select: , Separate memories for data and instructions, One shared memory, Virtual memory only, Secondary storage] 2. Bus ConfigurationVon Neumann architecture uses: Answer 3 Question 10[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 10[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 10[select: , The same pathway, Separate pipelines, Dedicated execution buffers, Read-only bus] Instruction and data in Harvard architecture travel through: Answer 6 Question 10[select: , Independent pathways, Shared execution lanes, Cache-only paths, Virtual routing] 4. Execution Efficiency Von Neumann architecture is generally: Answer 7 Question 10[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 10[select: , Faster due to parallel access, Slower due to single bus, Less efficient with branching, Dependent on virtual memory]

This question asks you to compare Von Neumann and Harvard architectures across four aspects, with two sub-parts per aspect, totaling eight fill-in-the-blank statements. I will discuss each item in turn, explaining why the correct characteristic fits each architecture and why the alternative ideas are not appropriate. 1. Memory Organization — In the Von Neumann architecture, data and instructions are stored in a: - In Von Neumann systems, there is a single shared memory space used for both instructions (code) and data. This is the hallmark of the architecture, which leads to the classic von Neumann bottleneck where the instruction fetch and data access compete for the same bus and memory bandwidth. The alternative of separ......Login to view full explanation
