PC users should know that there is not one but several types of memory.Basic concepts about this, we inoculated another first science lessons in school.So, many will remember that in addition to the computer's memory, there is still a virtual memory.This concept is inherent in most modern operating systems.It is easy to explain the widespread low cost and thus considerable advantages.After all, virtual memory helps increase CPU performance without any extra costs.What does it represent?
Nowadays, many computers use 32 or 64 megabytes of RAM.For a one-time implementation of many programs is catastrophically small amount.We are used to doing several things at once, so often invoked by the browser along with the postal services, adding to the music player and a text editor.Running together, these programs are of great load on the processor and RAM are not enough.Do not be in the system of its virtual counterpart, it would have to close down unnecessary processes.
The principle of
essence of virtual memory, in this case, is the following: computer searches the RAM data have not used in the work, and create copies of them on the hard drive.This, in turn, will free up additional space that will be used to download new programs and applications.The process of copying is automatic, which means that users do not even suspect.Or they find that their computer memory will suffice for a hundred or two applications.In fact, every call to a virtual memory degrades performance.
If this happens often, the owner of the computer simply does not notice freezes the machine.But the constant use of virtual memory can significantly affect the operation.Therefore, such an important condition for a good performance was and will be the number of "RAM".If it's enough, then slow down less detrimental effect: we see only a slight pause when you change tasks performed.Also, to preserve the performance and privacy of users need to know how to clean the virtual memory.
Why do it
When using virtual memory uses so-called swap file.It stores all the collected data about the computer and its owner.It's quite risky, as particularly dangerous viruses can reach up to him.Therefore, to prevent undesirable consequences and to protect themselves from the threat, so it is important to remember how clean the virtual memory.The best way to do it periodically.
How to clean the virtual memory Windows XP
In this system, there is a feature that allows for automatic cleanup, but initially it is disabled.In order not to carry out the tedious procedure of manually (the more that you have to do it consistently), it is wise to take advantage of this built-in function.So, how to clean the virtual memory on Windows.
First we need to go through the start menu in the control panel.There we need the icon "Administration".By clicking on it twice left mouse button, a new window opens.It is necessary to find the Local Security Policy tab and go to it.The window will be named "Local Security Settings."It will choose the new local policies and security settings.
where attention should be paid to the option "Shutdown: Clear virtual memory paging file."Clicking on the right mouse button, select Properties.There are only two provisions included in the change and save your choice.Now we know how to clean the virtual memory.It is necessary to restart your computer twice (!) To make the changes take effect: when the swap file will be automatically purged.
