Section B -1 - Approaches to Computer Architecture - Compute

What architecture uses separate memory spaces for data and instructions?

• Von Neumann Architecture

• Harvard Architecture

• Uniform Memory Access Architecture

• Non-Uniform Memory Access Architecture

Which of the following is a benefit of the stored program model?

• We can get much more powerful processing capabilities at a lower cost than a single powerful device.

• The system bus can fetch instructions quickly enough to make efficient use of the CPU.

• Computers can be general-purpose as we can modify the program stored in memory.

• The computer is more scalable, allowing us to add more CPUs without a bottleneck.

What stored program model architecture does the following image best represent?

• Von Neumann Architecture

• Harvard Architecture

• Uniform Memory Access Architecture

• Non-Uniform Memory Access Architecture

Which of the following statements about the Von Neumann architecture are true?

Choose two options.

• We use two different memory spaces, one for instructions and one for data.

• Both program instructions and data are stored in the same format.

• Von Neumann processors will have a number of registers on the CPU for storing some data and instructions.

• Each processor will have it’s own memory, memory controller and memory bus.

What is cluster computing?

• Where more than one computer can access the resources of a single powerful supercomputer.

• Where a computer has more than one central processing unit.

• Where a processor can access program instructions and data from two separate memory spaces.

• Where more than one computer is connected together and will appear & perform as a single system.

Most of the most powerful modern supercomputers in the world use cluster computing.

• True

• False

What is Uniform Memory Access?

• Where more than one computer is connected together and will appear & perform as a single system.

• Where all of the CPUs in a multi-CPU system will use their own separate memory, memory controller and memory bus.

• Where all of the CPUs in a multi-processor system will use the same memory, memory controller and memory bus.

• Where a computer can perform multiple processing tasks simultaneously.

Which of the following statements regarding Non-Uniform Memory Access are true?

Choose two options.

• Separate memory spaces are used for program instructions and data.

• Each processor will have it’s own memory, memory controller and memory bus.

• It is much more scalable when adding CPUs than Uniform Memory Access.

• CPUs are connected together through a very fast local area network.
