The Difference between 32 bit and 64 bit Architecture and Application Support
Hi,
I'm posting this question to get clear understanding of the 64 bit Architecture of the Computer.
Its because i'm so confused.
What's the difference between 32 bit and 64 bit architecture?.
I have seen some applications , those are indicated on CD that supports only 32 bit but still works on 64 bit architecture?..I don't understand how is that.
There is two system32 folder in 64 bit architecture..Why is that?..
Thanks for your answer in Advance.

The SYSWOW64 service in Windows will automatically map programs to the right version.
So if a 32-bit program attempts to load "C:\WINDOWS\System32\kerne
