G9_Computer Architecture

What are the main components of the Von Neumann architecture?

• CPU, memory, input/output devices, and control unit

• CPU, GPU, RAM, and motherboard

• Keyboard, mouse, monitor, and printer

• Hard drive, SSD, USB, and Ethernet cable

Explain the concept of 'stored-program concept' in Von Neumann architecture.

• Instructions are stored in memory but data is stored in the CPU.

• Data and instructions are stored in separate memory and cannot be manipulated together.

• Data is stored in memory but instructions are stored in the CPU.

• Data and instructions are stored in the same memory and can be manipulated in the same way.

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

• Manages the storage of data in the CPU

• Controls the input and output devices of the computer

• Handles the network connections of the CPU

• Manages the execution of instructions and controls the flow of data within the CPU

Describe the function of the arithmetic logic unit (ALU) in Von Neumann architecture.

• Generates random numbers

• Performs arithmetic and logical operations on data

• Manages input and output devices

• Stores data in memory

What is the purpose of the memory unit in Von Neumann architecture?

• To store both data and instructions for the CPU to access and execute.

• To provide power to the CPU

• To cool down the CPU

• To display output on the monitor

Explain the term 'fetch-execute cycle' in the context of Von Neumann architecture.

• The fetch-execute cycle is the process of encrypting program instructions in memory

• The fetch-execute cycle is the process by which a computer retrieves program instructions from memory, decodes them, and then carries out the instructions.

• The fetch-execute cycle is the process of deleting program instructions from memory

• The fetch-execute cycle is the process of printing out the program instructions

Discuss the limitations of Von Neumann architecture.

• The limitations of Von Neumann architecture include the inability to process data efficiently

• The limitations of Von Neumann architecture include the lack of storage capacity

• The limitations of Von Neumann architecture include the lack of compatibility with modern software

• The limitations of Von Neumann architecture include the bottleneck of the shared bus and the inability to execute multiple instructions simultaneously.

How does Von Neumann architecture handle instructions and data?

• It uses a single memory unit for only program instructions.

• It uses a single memory unit for both program instructions and data.

• It doesn't use any memory unit for instructions and data.

• It uses separate memory units for instructions and data.

Explain the significance of the Von Neumann architecture in modern computer systems.

• It was designed to be incompatible with modern software

• It introduced the concept of storing program instructions and data in the same memory unit.

• It focused on separating program instructions and data into different memory units

• It was the first computer architecture to use quantum computing

Data and instructions are transferred from these devices.

• CPU

• Main Memory

• Input devices

• Output devices

• Bus
