Today application is getting bigger and bigger. Therefore, it requires a bigger system memory in
order for the system to hold the application data, instruction, and thread and to load it. The system needs to copy the application data from the HDD into the system memory in order for it to process and execute the data.
Once the memory gets filled up with data, the system will stop loading the program. In this case, users need to add more memory onto their system to support that intense application. However, adding more system memory costs the money and the normal user only needs to run the the intense application that requires the memory only for one or two days. Therefore, virtual memory is introduced to solve that type of problem.
Terminology & Explanation
There are two types of memory, which are as follows:
* System Memory is a memory that is used to store the application data and instruction in order for the system to process and execute that application
data and instruction. When you install the memory sticks to increase the system RAM, you are adding more system memory. System Memory can be known as either
the physical memory or the main memory.
* Virtual Memory is a memory that uses a portion of HDD space as the memory
to store the application data and instruction that the system deemed it doesn't need to process for now.
Virtual Memory can be known as the logical memory, and it controls by the Operating System, which is Microsoft Windows.
Adding the Virtual Memory can be done in system configuration.
If you would like to determine how much the Virtual Memory is for your system and/or would like to configure and add more virtual memory,
follow the procedure that is shown below. The following procedure is based on windows XP Professional.
1-1) Go to right-click My Computer and choose Properties
1-2) In the System Properties dialog box, go to Advanced tab
1-3) Click Settings button that is from the Performance frame
1-4) Once the Performance Options shows up on the screen, go to Advanced tab
1-5) Under the Advanced tab, click the Change button from the Virtual Memory frame to access to the Virtual Memory setting
Then the Virtual Memory dialog box appears on the screen.
In there, you are able to check how much the Virtual Memory you set.
If you would like to modify the size of Virtual Memory, follow the procedure that is shown below.
2-1) In there, select the drive letter that is used to install the Operating System
2-2) Choose the option that says, "Custom Size:"
Once you choose that option, the setting for Initial Size and Maximum Size become available for you to set. Initial Size (MB) means the actual size of Virtual Memory, and Maximum Size (MB) means the maximum size of Virtual Memory that is allowed to use.
Let's say if your system contains 512 MB of RAM, then the ideal setting for the Virtual Memory is as follows:
CODE
Initial Size (MB): 768
Maximum Size (MB): 1500
Once you are happy with that Virtual Memory size, click the Set button from Paging file size for selected drive to apply the setting for
the Virtual Memory size. Then click the OK button to apply the setting.
That's where you can manage and configure for the size of Virtual Memory.
Additional Information
* To maintain the good overall system performance, you should be using the default size of actual
size for Virtual Memory and the triple the value of the size of the main memory for the maximum size of Virtual Memory.
If you find that main memory plus virtual memory is not big enough to load the intensive application, then you will need to add more main memory onto your system.
