Von Nuemann Flashcards
Who is the Von Neumann architecture named after?
John von Neumann
What are the main components of the Von Neumann architecture?
Central Processing Unit (CPU), Memory, Input/Output devices
True or False: The Von Neumann architecture uses a single memory space for both instructions and data.
True
Fill in the blank: The Von Neumann architecture operates on the principle of ________ execution.
sequential
What is the primary role of the Control Unit in the Von Neumann architecture?
To direct the operation of the processor and manage the execution of instructions.
Multiple Choice: What does the ALU stand for in the context of the Von Neumann architecture? A) Arithmetic Logic Unit B) Advanced Logic Unit C) Automatic Logic Unit
A) Arithmetic Logic Unit
What does memory in the Von Neumann architecture store?
Both data and program instructions.
True or False: In the Von Neumann architecture, the CPU can execute multiple instructions simultaneously.
False
What is one disadvantage of the Von Neumann architecture?
The Von Neumann bottleneck, which limits the speed of data transfer between the CPU and memory.
Fill in the blank: The concept of ________ is a key feature of the Von Neumann architecture that allows programs to manipulate data.
stored programs
What type of memory does the Von Neumann architecture typically use?
Random Access Memory (RAM)
Multiple Choice: Which of the following is NOT a characteristic of Von Neumann architecture? A) Single memory space B) Parallel processing C) Sequential instruction processing
B) Parallel processing
What is the purpose of the Program Counter in the Von Neumann architecture?
To keep track of the address of the next instruction to be executed.
True or False: The Von Neumann architecture supports the use of multiple types of data formats.
True
What is the function of Input/Output devices in the Von Neumann architecture?
To allow the computer to communicate with the outside world.
Fill in the blank: The Von Neumann architecture was first described in the year ________.
1945
What is a key advantage of the Von Neumann architecture?
Simplicity and ease of use due to its single memory structure.
Multiple Choice: Which of the following best describes the Von Neumann bottleneck? A) Limited memory size B) Slow CPU speed C) Data transfer limitations between memory and CPU
C) Data transfer limitations between memory and CPU
What does the term ‘fetch-execute cycle’ refer to in the Von Neumann architecture?
The process of retrieving an instruction from memory and executing it.
True or False: The Von Neumann architecture is commonly used in modern computing systems.
True
What is the significance of the stored-program concept in the Von Neumann architecture?
It allows programs to be stored in memory and executed by the CPU, enabling flexibility and efficiency.
Fill in the blank: The Von Neumann architecture is often contrasted with the ________ architecture.
Harvard
What kind of operations does the Arithmetic Logic Unit (ALU) perform?
Mathematical and logical operations.
Multiple Choice: Which of the following is a limitation of the Von Neumann architecture? A) High performance B) Flexibility C) Bottleneck effect
C) Bottleneck effect
