Useful information about 64 Bit Software

New processors arriving from Apple and Advanced Micro Devices suggest 64-bit computing. All latest software and data process run against an inherent memory restriction. A 32-bit software can allocate a maximum of 2GB memory, per running process, irrespective of how much memory is available on the system. Practically, this means XML files larger than 200MB can never be opened. With a 64-bit, the memory limitation is not the same. Presently, 64-bit interpretations of MS Windows 7 affirm up to 192GB of the installed memory.

In most cases, the XML file size is restricted only by the physical memory set up. 64-bit systems, process data's virtually even without enough physical memory, but quiet slowly. To find out, on what processor your computer system is working, just go to the control panel and click on the switch to classic view. You will now see an icon called system which will give you the details on processor. One major issue underlying to 64-bit software is that its memory requirements.

It obviously needs a lot of memory than a 32-bit application, because the memory size, pointer and other structures reflexively become bigger. The memory consumption grows by 50% when a 64-bit software is used and hence the user should have a minimum of 4GB memory installed before proceeding with 64 bit software. Generally, 64 bit application needs a 64 bit driver for database connection. Some important concerns are

• ODBC - Only 64-bit variants of ODBC can be used with 64-bit applications.
• Microsoft Access - It cannot exist together with a 32-bit version of MS Office. Users need to install a 64-bit ACE driver to open access database.
• Other database - They do not have any drivers and even if a driver is installed it pops up with an installation error message.
• Browser Plug-ins - Currently only Internet explorer is available in both versions.
