A-level Contemporary processors

In the context of von Neumann architecture, what does the term 'shared memory space' refer to?

• A memory area that is inaccessible during processing.
• A memory area that stores both instructions and data.
• A memory area where only data is stored.
• A memory area where only instructions are stored.

Which of the following best describes the memory structure of von Neumann architecture?

• Instructions and data are stored in separate memory units.
• Instructions are stored on a hard drive while data is in memory.
• Instructions and data are stored in the same memory space.
• Instructions are stored in a cache while data is in RAM.

Which of the following statements accurately describes the fetch-execute cycle in von Neumann architecture?

• Multiple instructions are fetched and executed simultaneously.
• Instructions are fetched and executed in a linear sequence.
• Data is fetched while instructions are executed.
• Instructions are stored in a separate cache.

In which architecture is a single control unit responsible for executing one instruction at a time?

• Harvard architecture
• Contemporary architecture
• Von Neumann architecture
• Distributed architecture

Which of the following statements about the fetch-execute cycle in von Neumann architecture is correct?

• It allows for simultaneous execution of multiple instructions.
• It can execute multiple instructions in parallel.
• It involves fetching an instruction, decoding it, and then executing it.
• It requires separate memory for instructions and data.

What is the primary limitation of von Neumann architecture?

• It cannot store data and instructions simultaneously.
• It has no memory management capabilities.
• It is too complex for modern applications.
• It requires multiple processors to function.

What is a common misconception about Harvard architecture?

• It uses a single memory unit for both instructions and data.
• It is only used in older computing systems.
• It cannot execute instructions and read data simultaneously.
• It is more complex than von Neumann architecture.

Which of the following accurately describes the memory organization in Harvard architecture?

• Instructions are stored in a cache while data is in the main memory.
• Instructions are fetched from a hard drive while data is in RAM.
• Instructions and data are stored in separate memory units.
• Instructions and data are stored in the same memory space.

What is a significant advantage of Harvard architecture over von Neumann architecture?

• It uses a single control unit.
• It allows for a simpler design.
• It enables simultaneous reading and writing of data.
• It requires less memory.

Which type of architecture is typically associated with RISC processors?

• Harvard architecture
• Contemporary architecture
• Distributed architecture
• Von Neumann architecture
