Cache memory is an processor inbult memory, which keeps the frequently used data in it, So that the processor pickups the data from Cache memory and no need to searchthe RAM and harddisk. So the processor perfomance will get increased.

A cache is a temporary storage area where frequently accessed data can be stored for rapid access. Once the data is stored in the cache, future use can be made by accessing the cached copy rather than re-fetching or recomputing the original data, so that the average access time is shorter. Cache, therefore, helps expedite data access that the CPU would otherwise need to fetch from main memory.

A cache is a block of memory for temporary storage of data likely to be used again. The CPU and hard drive frequently use a cache, as do web browsers and web servers.

A cache is made up of a pool of entries. Each entry has a datum (a nugget of data) which is a copy of the datum in some backing store. Each entry also has a tag, which specifies the identity of the datum in the backing store of which the entry is a copy.

When the cache client (a CPU, web browser, operating system) wishes to access a datum presumably in the backing store, it first checks the cache. If an entry can be found with a tag matching that of the desired datum, the datum in the entry is used instead. This situation is known as a cache hit. So, for example, a web browser program might check its local cache on disk to see if it has a local copy of the contents of a web page at a particular URL. In this example, the URL is the tag, and the contents of the web page is the datum. The percentage of accesses that result in cache hits is known as the hit rate or hit ratio of the cache.

The advantage of cache memory is that the CPU does not have to use the motherboard’s system bus for data transfer. Whenever data must be passed through the system bus, the data transfer speed slows to the motherboard’s capability. The CPU can process data much faster by avoiding the bottleneck created by the system bus

Outlook express freezes


There are many things that might cause your PC or any application in your PC like outlook express to run slowly or freeze or even restart at time and then. It could be a fragmented disk, fragmented registry; a virus, Trojan, or spy ware; high CPU and/or utilization due to too many programs running; high disk I/O; caused by an infection.

To check your CPU and memory utilization, run Task Manager. You can start Task Manager by pressing CTRL+ALT+DEL and then clicking on the Task Manager Button. In Task manager, click on the Performance tab and check CPU Usage and PF Usage. PF Usage is an indicator of memory usage. If one or both of these is high, click on the Processes tab, and sort the columns by CPU or Memory to see what processes are consuming the resource. If you are not sure what the process "Image name" is for, Google the name and you should find what the process is for.

If your CPU and memory usage are reasonable, then you may have a different issue. Even if you running anti-virus software, it may be beneficial to scan your PC with another scanner to check for viruses. No anti-virus software is 100% perfect at catching everything. Here are a few good free online virus scanners that you can run to check your PC:

So here is the best solution that I can suggest for you is to scan your
PC with a very strong antivirus, here is the link to get it.Its very good.

To clean up registry there is another very good application which will keep your PC registry out of trouble caused from spywares.

Memory full while i'm browsing


before this happens open task manager (press ctrl alt delete simultaneously).
under performance tab see cpu usage and memory.
cpu usage should be about 2% normally.
memory should not be full.

if cpu usage seems high then a virus is trying this act or you have unwanted programs which you my end from startup.

second case is of some problem in ram

Now right click My Computer and go to properties tab.
click 'Advanced' tab then under performance menu click on 'settings'
goto 'Advanced' click on 'change' and increase your virtual memory to 2048 in both spaces.
now restart windows.

To quickly restart windows press CNTRL+ALt+DEL
inside task manager you will find all the open applications .
right click on each applicaion and click on end process tree then ok

Close all your apps like this and you will find your windows a lot faster and now you can reboot or turn off your windows as usual from start button.

I upgraded the Android system for my sanyo zio and now i can't recieve any text messeges cause it says that the memory is full and it also says that my phone memory is full eventhough iv'e been erasing...


Hi,

It seems most of you applications are stored in the Phone Memory and/or your application data is taking up lot of memory. You actually don't have to erase/uninstall applications. Please consider performing the following steps:

  1. Go to Settings --> Applications --> Manage Applications. In this Menu you'll be shown a list of applications. Use the Menu Button to "Sort by Size" and get a list of the applications sorted from high memory usage to low (phone memory). Once this is done, you'll be able to view the memory being used by each of the applications. Click on the applications which you see are consuming more memory and then use the "Clear Data" button to clean up the data being stored by the applications to free up memory. This clears up any cache, cookie, temp files associated with the applications. Depending on your android version, you may also see an additional button "Move to SD Card". The best option to get more space would be to use this button and move the application to the 4 GB SD Card storage.
  2. Optional Step if you do not have "Move to Phone/SD Card" option available - From the Android Market, download and install "App 2 SD Free". Once done, this application should help you free up a lot of space by moving applications from your phone memory to the SD card.
Hope this was helpful. If so, please consider rating this solution.

-thanks,
M

My operating system is windows 98, i recently upgraded my memory card from i gigabyte to 2 gigs, but every time i boot my computer there is an error message low in memory, the question is; how can i boot...


CAUSE:
The Windows 32-bit protected-mode cache driver (Vcache) determines the maximum cache size based on the amount of RAM that is present when Windows starts. Vcache then reserves enough memory addresses to permit it to access a cache of the maximum size so that it can increase the cache to that size if needed. These addresses are allocated in a range of virtual addresses from 0xC0000000 through 0xFFFFFFFF (3 to 4 gigabytes) known as the system arena.

On computers with large amounts of RAM, the maximum cache size can be large enough that Vcache consumes all of the addresses in the system arena, leaving no virtual memory addresses available for other functions such as opening an MS-DOS prompt (creating a new virtual machine).

WHAT CAN U DO?
To work around this problem, use one of the following methods:
  • Use the MaxFileCache setting in the System.ini file to reduce the maximum amount of memory that Vcache uses to 512 megabytes (524,288 KB) or less. For additional information about how to use the MaxFileCache setting, click the article number below to view the article in the Microsoft Knowledge Base: 108079 (http://support.microsoft.com/kb/108079/EN-US/ ) 32-Bit File Access Maximum Cache Size
  • Use the System Configuration utility to limit the amount of memory that Windows uses to 512 megabytes (MB) or less.For additional information about how to use the System Configuration utility, click the article number below to view the article in the Microsoft Knowledge Base: 181966 (http://support.microsoft.com/kb/181966/EN-US/ ) System Configuration Utility Advanced Troubleshooting Settings
  • Reduce the amount of memory that is installed in your computer to 512 MB or less.
