Which of the following terms refers to the area of the hard drive used for virtual memory?
A. virtual file
B. data file
C. swap file
D. volatile file
Answer: C. Swap File
Explanation: Swap files provide some space for programs for the computer and virtual memory.
The term that refers to the area of the hard drive used for virtual memory is a swap file. The correct option is c.
What is virtual memory?
Operating systems use virtual memory, a different set of memory addresses, along with the hardware reserve to increase the total number of addresses (actual memory plus virtual memory). The virtual addresses are changed into actual memory addresses when the application is really run.
A swap file is a hard drive space that serves as a computer's virtual memory expansion (RAM). A computer can use more memory than what is actually installed in it by employing a swap file.
In order to save space, data from RAM is "swapped" onto a file or area on the hard drive. Data is switched back and forth from the RAM to the swap file as you switch between the apps.
Therefore, the correct option is c. swap file.
