General Information:

This article refers to the debate of 32-bit versus 64-bit usage for Windows. Windows has the ability to run a 32-bit version or a 64-bit version. These designations are used to describe the way in which theCPUhandles information and basically how muchRAMthe CPU can store. The user can decide which version would be better suited for their individual needs.

Running a 64-bit version of Windowsdoes not necessarily mean that the computer will run more efficiently. This can actually hinder the speed of the user's computer depending on the installed programs, drivers, and the computer’s processor. In order to fully utilize a 64 bit processor, the older programs and drivers installed on the computer need to be updated to 64-bit, since 32-bit programs &drivers are not supported by the 64-bit version of Windows.

Benefits of 64-Bits:

The main perks gained from installing a 64-bit version of Windows are the ability to access RAM above the 4-GB range and the advanced security features. The access to more memory allows for more efficiency when administering processes and consequently improves performance of theOS.While there are advantages to installing a 64-bit version of Windows, there are a few drawbacks as well. Although trends may be shifting, computers were historically shipped with the 32-bit processors. With these computers having a 32-bit architecture, the programs and applications written for them also have 32-bit architecture. For this reason, running a 32 -bit application on a 64-bit operating system will not be the optimal choice in relation to performance.

32-bit drivers also may not be compatible with the 64-bit operating system. Users need to upgrade the driver's by switching to 64-bit when upgrading. Another potential obstacle is that older CPU architectures may not be supported whatsoever.
