Q: Which type of operating systems should I choose: 64-bit or 32-bit?
A: The terms 32-bit and 64-bit refer to the way a computer's processor handles information. The 64-bit version of operating systems handle large amounts of random access memory (RAM) more effectively than a 32-bit system. If you don't have any custom build software application, it is better to choose the 64-bit system. If you have a customer build software application (software that is not from our default install), please check with us , your software vendor or your programmer to see if it is compatible with 64-bit system.
