    30s
  • Q4
    What is the role of the Control Unit (CU) in a CPU?
    To store data temporarily
    To direct the operation of the processor and manage the execution of instructions
    To increase the speed of the RAM
    To perform arithmetic operations
    30s
  • Q5
    How does virtual memory utilize the hard drive?
    By creating backups of RAM
    By speeding up data access
    By storing files permanently
    By using a paging system to swap data in and out

  • Q6
    What is a common consequence of relying heavily on virtual memory?
    The computer will freeze permanently
    The CPU will become damaged
    Data will be lost immediately
    The computer may experience slower performance
