06 - Virtual Storage

 1. What is virtual storage?

  Treating all storage media as a single pool of storage

  Data that is not stored in binary form

  A type of translucent SSD

  An unresolved problem in computer science

 2. Virtual memory uses other storage as an extension of memory to free up RAM.



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

  Fritz-Rudolf Güntsch

  Bill Gates

  Mark Zuckerberg

  John Von Neumann

 4. What are virtual memory addresses?

  A reference to a specific memory location

  The geographical location of a data centre

  A memory address that is randomly generated

  A place in virtual reality

 5. Complete the blank: virtual memory addresses are usually divded into blocks called ____.





 6. The memory management unit translates virtual addresses into physical addresses.



 7. What is thrashing?

  A type of RAM error

  Saturation of the virtual memory

  A type of printer error

  Overheating of the hard disk

 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.



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

  Because virtual storage is too complicated

  In order to reduce the response time

  Because the response time is not important

  Because cooling would occur
