1.1

• What does 'CPU' stand for?

  Central Processing Unit
• What is the purpose of the CPU?

  To process data and instructions
• What is the fetch-execute cycle?

  A process of repeating data handling
• What does the Control Unit (CU) do?

  Sends control signals to direct CPU operation
• What does the ALU stand for?

  Arithmetic and Logic Unit
• What operations does the ALU perform?

  Simple calculations and logical operations
• What is a register?

  A temporary storage space for instructions
• What is the purpose of cache memory?

  To temporarily store frequently accessed data
• How is cache memory different from registers?

  Cache is slower than registers but faster than RAM
• What is computer architecture?

  The design and structure of a computer
• What is the most common type of computer architecture?

  Von Neumann architecture
• Who developed the concept of a stored program computer?

  John von Neumann
• What does Von Neumann architecture store in memory?

  Both program instructions and data
• How does Harvard architecture differ from Von Neumann architecture?

  Harvard has separate memories for instructions and data
• What are buses in computer architecture?

  Pathways for data transfer between components
• What are the main components of the CPU?

  • Control Unit (CU)
  • Arithmetic and Logic Unit (ALU)
  • Registers
  • Cache memory
• What are the purposes of the CPU components?

  • Control Unit: Directs CPU operations
  • ALU: Performs calculations and logical operations
  • Registers: Temporary storage for instructions
  • Cache memory: Stores frequently accessed data
• What are the key features of Von Neumann architecture?

  • Stores both program instructions and data in RAM
  • Developed by John von Neumann
  • Uses a single memory for both instructions and data
• What are the differences between Von Neumann and Harvard architectures?

  • Von Neumann: Single memory for instructions and data
  • Harvard: Separate memories for instructions and data
