virtual memory + what does the future hold for memory

Página 1

If your computer lacks the

random access memory (RAM) needed to run a program or operation, Windows uses

virtual memory to compensate.

Virtual memory combines your computer’s RAM with

temporary space on your hard disk. When RAM runs low, virtual memory moves data

from RAM to a space called a paging file. Moving data to and from the paging

file frees up RAM so your computer can complete its work.

The more RAM your computer has, the faster your

programs will generally run. If a lack of RAM is slowing your computer, you

might be tempted to increase virtual memory to compensate. However, your

computer can read data from RAM much more quickly than from a hard disk, so

adding RAM is a better solution.
