Open Ended

What prior knowledge do you have about how a CPU works or its main components?

Multiple Choice

Why is understanding the components of the CPU important for learning about computer systems?

• Because the CPU controls all operations in a computer

• Because the CPU is only used for gaming

• Because the CPU is not important for computers

• Because the CPU is only used for storage

Open Ended

Describe how computers operated before the introduction of the Von Neumann architecture.

Multiple Choice

What is the main idea behind the Von Neumann architecture that made modern computers more versatile?

• Storing instructions in memory alongside data

• Using only physical switches for instructions

• Making computers larger and less efficient

• Eliminating the need for memory

Multiple Select

Which of the following are key steps in the Von Neumann architecture for processing instructions?

• Instructions are fetched from memory one at a time
