  A type of translucent SSD

  Treating all storage media as a single pool of storage

  An unresolved problem in computer science

  Data that is not stored in binary form

  TRUE

  FALSE

 3. Who first devised the concept of virtual storage in 1956?

  Fritz-Rudolf Güntsch

  John Von Neumann

  Mark Zuckerberg

  Overheating of the hard disk

  A type of RAM error

  Saturation of the virtual memory

  A type of printer error

 8. Thrashing occurs if the CPU…

  speeds up too rapidly

  spends more time exchanging data in primary and secondary storage than processing applications

  becomes too warm in extreme conditions

  is scratched or otherwise damaged

 9. Thrashing can be stopped by closing down applications.

  FALSE

  TRUE

 10. Why do embedded systems often not use virtual storage?

  Because virtual storage is too complicated

  Because cooling would occur

  In order to reduce the response time

  Because the response time is not important
