Virtual Memory
What is it?
What is it?
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 to complete its work.
Advantages and Disadvantages
An advantage is that you can run more applications at once. You can run larger applications with less real RAM. However appliactions run slower! It takes more time to switch between applications and you have less hard drive space for your use.
How does the change in memory lead to innovative computer design?
Memory is always changing and evolving. In size and shape. So it will allow this technology to be better.
