What is the main principle of Von Neumann architecture?

• Single instruction execution

• Direct memory access

• Fixed-program concept

• Stored-program concept

List the five main components of a Von Neumann computer system.

• Graphics Processing Unit (GPU)

• Network Interface Card (NIC)

• Power Supply Unit (PSU)

• Central Processing Unit (CPU), Memory, Input devices, Output devices, Storage

How does the memory in a Von Neumann architecture function?

• Memory only stores data and does not hold any instructions.

• Memory is accessed randomly by the CPU without a specific order.

• Memory in a Von Neumann architecture functions as a unified storage for both data and instructions, accessed sequentially by the CPU.

• Memory is divided into separate sections for data and instructions.

What is the role of the control unit in a Von Neumann architecture?

• The control unit directs the operation of the processor and coordinates the execution of instructions.

• The control unit manages the power supply to the processor.

• The control unit stores data temporarily for quick access.

• The control unit handles input and output operations directly.

Explain the difference between primary and secondary storage.

• Primary storage is non-volatile and secondary storage is volatile.

• Primary storage is only used in mobile devices, while secondary storage is used in desktops.

• Primary storage is used for long-term data retention, while secondary storage is for immediate access.

• Primary storage is volatile and used for immediate access, while secondary storage is non-volatile and used for long-term data retention.

What types of input devices are commonly used in a Von Neumann system?

• Monitors

• Speakers

• Keyboards, mice, scanners, microphones

• Printers

Describe the output process in a Von Neumann architecture.

• Data is processed without fetching it from memory.

• Output devices are not involved in the Von Neumann architecture.

• The output process only involves sending data directly to the CPU.

• The output process involves fetching data from memory, processing it, and sending it to an output device.

How does the fetch-decode-execute cycle work in this model?

• The cycle involves only fetching data from memory.

• The fetch-decode-execute cycle does not involve memory access.

• The fetch-decode-execute cycle involves fetching an instruction from memory, decoding it to understand the operation, and executing the instruction.

• Instructions are executed before they are decoded.

What are the advantages of using Von Neumann architecture?

• High power consumption due to parallel processing

• Advantages of Von Neumann architecture include simplified design, efficient memory usage, and ease of programming.

• Complex design requiring multiple processors

• Limited programming languages supported

In what ways has the Von Neumann architecture influenced modern computing?

• It introduced the concept of quantum computing.

• It focused solely on hardware design without considering software.

• The Von Neumann architecture has influenced modern computing by enabling stored-program computers, establishing CPU design, and promoting software flexibility.

• It eliminated the need for memory in computers.
