Happy International Peace Day!

Here, though my blog maintenance is not complete yet, I just came around to wish all my friends and pals a Happy International Peace Day!

With that spirit we come together today to celebrate the International Peace Day, a day of reflection and a time to acknowledge the need for peace in our ever conflicting world.

The International Day of Peace occurs all around the world on the 21st of September, it is an annual celebration and it is dedicated to peace, or specifically the absence of war, such as might be occasioned by a temporary ceasefire in a combat zone. It is celebrated by many nations, especially political groups and military groups.

I hope your day is peaceful and happy. And I also hope for peace and happiness all over the world! May the peace and happiness always remain in our heart!
Thanks!

Virtual Memory too low - Solution Here


What you will do when your Virtual Memory is too low ? This Article talks about anything about the virtual memory and how much virtual memory you need for your system, so that you will not face the problem again.

Introduction & Background

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:

1) 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.

2) 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.

Information & Facts or Implementation

Virtual Memory is a HDD space that uses some portion of it as the memory. It is used to store application data and instruction that is currently not needed to be process by the system.cs

During the program loading process, the system will copy the application data and its instruction from the HDD into the main memory (system memory). Therefore the system can use its resources such as CPU to process and execute it. Once the system memory gets filled up, the system will start moving some of the data and instruction that don't need to process anymore into the Virtual Memory until those data and instruction need to process again. So the system can call the next application data and instruction and copy it into the main memory in order for the system to process the rest and load the program. When the data and instruction that is in the Virtual Memory needs to process again, the system will first check the main memory for its space. If there is space, it will simply swap those into the main memory. If there are not any space left for the main memory, the system will first check the main memory and move any data and instructions that doesn't need to be process into the Virtual Memory. And then swap the data and instruction that need to be process by the system from the Virtual Memory into the main memory.

Having too low of Virtual Memory size or large Virtual Memory size (meaning the size that is above double of the system memory) is not a good idea. If you set the Virtual Memory too low, then the OS will keep issuing an error message that states either Not enough memory or Virtual too low. This is because some portion of the system memory are used to store the OS Kernel, and it requires to be remain in the main memory all the time. Therefore the system needs to have a space to store the not currently needed process data and instruction when the main memory get filled up. If you set the Virtual Memory size too large to support the intensive application, it is also not a good idea. Because it will create the performance lagging, and even it will take the HDD free space. The system needs to transfer the application data and instruction back and forth between the Virtual Memory and the System Memory. Therefore, that is not a good idea. The ideal size for the Virtual Memory is the default size of Virtual Memory, and it should not be exceed the value of the triple size of system memory.

Solution

To determine how much virtual memory you need, since the user's system contains the different amount of RAM, it is based on the system. By default, the OS will set the appropriate size for Virtual Memory. The default and appropriate size of Virtual Memory is:
Amount_Of_System_Memory * 1.5 = Default_Appropriate_Size_Of_Virtual Memory
For example, if your system contains 256 MB of RAM, you should set 384 MB for Virtual Memory.
256 MB of RAM (Main Memory) * 1.5 = 384 MB for Virtual Memory
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:
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.

Optimize your Hard Disk Performance

No Matter what type of hard disk you have, here in this article you will find some helpful tips for you to get better speeds and increase the life of your hard disk.

Defragment your drive:
This is one of the often repeated tips, yet we say this again. . I think it is the most common reasons for making hard disk performance slow down. As the new files cannot be stored in contiguous clusters, the disk becomes fragmented when files are deleted and new files are written to the disk. Use the Windows defragmentation tool which comes default with your Operating system or a free tool like Auslogics Defragmenter which can be find here: http://www.auslogics.com/disk-defrag .

Use Power saving Options: The lesser you make your hard disk work, the longer it lasts. If you are used to leaving your PC idle while you step out, enable hard disk power off under Power Management or just Hibernate your PC which will switch power your hard disk off. However, do not use this option if you are going to be away for just a few minutes or you frequently take such breaks, as frequent start-stops can actually reduce the disk's life. Use it if you are going away for a couple of hours and you don't want to switch off and on your PC.

Avoid tilting : You should avoid this or otherwise moving your PC when the PC is on will led your hard disk to crush. Hard disks do not take too kindly to being moved around while they are working! And, if you hear a screeching noise from your PC that coincides with the hard disk activity indicator(usually the red or amber LED), it's time for you to backup immediately and be prepared for a new hard disk.

How to create an Invisible Folder in Windows Xp?

It's a simple nice trick. With this you can create an invisible folder that you can put on your desktop or within another folder. You can't see it but if you know where it is you can double-click it and view its contents. I don't know who created it, just thanks whoever you are.

So here it is:

1. Right click where ever you want the invisible folder to be, go to new, then click on folder.
2. Turn number lock on, select the name, and hold Alt and press 0160, then release Alt. This should make a character that looks like a space, but it isn't.
3. Now right click the folder you just made and go to properties. Then go to the Customize tab. Then press the Change Icon button. Scroll through the icons until you find one that has no image (a blank space in the icons, any one will do).
4. Hit OK and you have an invisible folder!

Now you can put anything you want in there... If you can't find it, just select the entire folder/desktop and there will be a little blue rectangle below the invisible icon (the folder).

NOTE: If you put it on your desktop it might show the folder for a second or two upon startup. For this reason I recommend putting it inside another folder.
