Virtual Memory Flashcards
When does virtual memory come into place?
When there isn’t enough space for the main memory to store large programs or lots of programs running at once.
What is multi-tasking in a computer sense?
When multiple instructions are running at once
How does virtual memory be created?
Computers are configured so part of the hard disk and solid state drive behaves like main memory
What does HDD stand for?
Hard Disk
What does SSD stand for?
Solid State Drive
Why is using virtual memory not ideal?
Access speed of SSD and HDD usually slower than RAM (main memory)
What is virtual memory used for?
It is used to store parts of parts of programs currently being run but parts actually being executed still need to be in the main memory
What happens when the processor gets the next part of the instruction?
Sections are swapped between virtual memory and main memory
What sometimes happens when parts of the instructions is swapped between the main memory an the virtual memory?
The swapping takes longer than the execution of the program
