What is the difference between bitween pagefile and virtual memory?
pagefile is the virtual memory
What is the optimal page file for 4096 gb?
The maximum usable pagefile for windows xp is 4gb The maximum usable pagefile for windows vista 32bit, is also 4gb. Now if you use XP or Vista 64 bit version, then the maximum is 32gb. Normally the ideal pagefile is exactly 1.5 times the amount of ram set for both maximum and minimum. So 512mg of ram, 768 should be the max and min pagefile setting. But since the 32 bit operating system is limited to 4gb, you should set it to 4096 max and min.
Which two types of memory make up the working memory of the computer?
Ram and pagefile.
What is the page file usage in the windows task manager?
PF Usage is an abbreviation for pagefile usage. Unfortunately the label is misleading as that is not what it is showing. This is actually the same as the commit charge. This can be more accurately thought of as potential pagefile usage: if everything in RAM that could be sent to the pagefile actually was, this is the space that would be required. A great deal of what is labeled "PF Usage" will actually be in RAM, not the pagefile. Actual pagefile usage, as shown in Performance Monitor, will typically be much lower. Memory management in modern operating systems is very complex. Do not try to read too much into what Task Manager might seem to be telling you. Chances are it does not mean what you think it does. Always remember this: Windows designers know more about memory management than you do. Windows know how it is using it's resources even if you do not. Larry Miller, Microsoft MCSA
Where the pagefile located?
The pagefile, often referred to as pagefile.sys, is a system file in Windows operating systems that acts as virtual memory. By default, it is located in the root directory of the system drive, typically the C: drive. Users can view or change its location through the System Properties under the Performance Options settings.
What is another term for a page files and why are page files used?
A pagefile is a system file that is used in place of RAM, or random-access memory. These are the "memory sticks" people refer to that are placed in your computer. Most computers today have 2 GiB of RAM. A pagefile is used when a computer does not have enough physical memory available. After the RAM is filled with data, the computer offloads some of the data (the data that isn't currently being used) in RAM to the hard disk, into the pagefile. It's also known as a swap file.
How you will be defining the size of memeory?
You need to be more specific. Defining what memory? Pagefile, virtual machine ram, physical ram?
Is virtual memory swap file?
Absolutely not! Virtual memory is a system that provides a virtual environment to applications that is independent of computer physical resources. The swap file (more corectly called the pagefile) serves only in a supporting role.
Where virtual memory is stored?
In the C:\pagefile.sys file. WRONG! That is a very common view but totally wrong. Virtual memory is a system that provides a virtual environment to applications that is completely independent of computer physical resources. This system is always in use and cannot be disabled. The system combines physical memory, many files on the hardisk, as well as the pagefile, to accomplish this. The pagefile serves only in a supporting role. I believe this is RIGHT (OS book page 149) Pagefile.sys is a hidden file stored in the root directory C. when using virtual memory.
What memory is the space on the hard drive to which the OS stores data if there isn't enough ram to hold all of the programs your trying to run?
It's called virtual memory. The space itself is called the pagefile (Windows) or swap area (Linux).
Can you use an SD card as a virtual memory page file on windows?
you can. but its a bad idea. page files are for frequent write operations, and flash memory has a limited write cycle lifetime. its like 500,000 cycles or so, but you will still wear it out pretty quickly as a page file. mount it as a folder under the main drive as c:\program files2\ or something if you want faster program load times, but really, its not worth it... yet. This has been tried and most people who have done this have noticed little if any performance gains. The reason is simple: The pagefile is used as temporary storage for data that has not been recently accessed, and presumably will not be needed often. If it is needed often it will be in RAM. In most cases access to the pagefile is infrequent enough that increasng it's performance has no real impact on system performance. If the pagefile is accessed enough to effect performance you need more RAM. Nothing else will male much difference.
Is it recommended to disable virtual memory when your system has 4 GB of RAM or more?
No it is not recommended. Always keep a VRAM. The system very often expects it to work properly as you never now how much memory a program might use. Some operating system (like Linux) can surely cope without it but it is not recommended. Actually, it is impossible to disable virtual memory in any modern system. You can disable the pagefile but this will not disable virtual memory. Virtual memory is NOT the pagefile, it is a system the includes physical RAM and almost every file on your hard disk. The pagefile was designed to improve performance by temporarily storing rarely used data, thus leaving more RAM available for more important uses. Unless you have a very specific need and you understand what you are doing it is best to leave pagefile settings on default. Windows designers know more about the pagefile and memory management than you do. In all modern Windows systems every process is assigned a 4GB virtual address space. The lower 2GB is private to the process while the upper 2GB is used by the system. Note: this is a virtual address space and is completely independent of how much RAM is in the system. Also note, the lower 2GB is private, it is not shared with other processes. RAM is asigned to a process's addres space according to need and availability. A typical system might have 30 or processes running at one time. Since each one has a 2GB virtual address space you have a potential RAM usage of 30 x 2GB + 2GB system for a total of 62 GB! Still think you don't need virtual memory?
