Original article posted by Patman is a copy of http://msdn2.microsoft.com/en-us/library/aa366527.aspx

From the article:

The virtual address space or 'memory window' of a 32-bit application is limited to 4GB (2^32-1 bytes),

Why the "-1"? 4GB is 2^32 bytes, not 2^32-1. Martin MMM

The bit pattern 0x00000000 is (not only) on MS Windows reserved for the NULL pointer in C. Hence this address is not usable to store objects there. :-) --RokerHRO (talk) 22:12, 11 January 2010 (UTC)Reply

Hello fellow Wikipedians,

I have just modified one external link on Address Windowing Extensions. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

Added archive https://web.archive.org/web/20140303011729/http://www-03.ibm.com/systems/kr/resources/systems_kr_x_techsupport_Tuning_xSeries_for_Performance.pdf to http://www-03.ibm.com/systems/kr/resources/systems_kr_x_techsupport_Tuning_xSeries_for_Performance.pdf

When you have finished reviewing my changes, you may follow the instructions on the template below to fix any issues with the URLs.
