Question 27 of 45
27. Question
1 pointsWhat does virtual memory provide to an operating system?Correct
Incorrect
The OS uses virtual memory when a computer does not have enough RAM available to run a program. Virtual memory moves data from RAM and places it in a paging file on the hard drive. A paging file is a place where data is stored until enough RAM is available to process the data. This process is much slower than accessing the RAM directly.Hint
