Explain the significance of the von Neumann architecture in modern computers.

• The von Neumann architecture revolutionized computer design by integrating memory and processing units.

• The von Neumann architecture focused on separating memory and processing units.

• The von Neumann architecture was developed in the 21st century.

• The von Neumann architecture is no longer used in modern computers.

How do output devices contribute to the user interaction with a computer system?

• Output devices contribute by slowing down the computer system

• Output devices contribute by providing feedback and enabling communication with the computer system.

• Output devices contribute by decreasing user accessibility

• Output devices contribute by increasing security risks

Describe the difference between volatile and non-volatile data storage.

• Volatile data storage retains data when power is off

• Non-volatile data storage loses data when power is off

• Volatile data storage is slower than non-volatile data storage

• Volatile data storage loses data when power is off, non-volatile data storage retains data.

What role does network hardware play in enabling communication between devices?

• Network hardware is only used for power supply to devices.

• Network hardware is designed to enhance device aesthetics.

• Network hardware enables the physical connection and transmission of data packets between devices.

• Network hardware is responsible for software updates on devices.
