Which of the following is not an aspect of Von Neumann Architecture?

• It makes use of the "Stored Program Concept"

• There is a processing unit that contains an Arithmetic and Logic unit

• Data and instructions are stored separate memories

• Instructions and data are transferred via single shared bus

Which of the following correctly describes the "Von Neumann Bottleneck"?

• The CPU is overclocked and becomes too hot

• There is insufficient memory to store instructions

• The CPU has data to process, but no instructions to carry this out

• The CPU is idle while it waits for data to be sent

Which of the following partially mitigates the impact of Von Neumann bottleneck?

• Through the use of the cache

• By adding more RAM to the computer

• By overclocking the CPU

• The Fetch Execute Cycle
