Application Development

The ‘flat memory model’ used by Windows NT provides a 4Gb logical address space which may be conceived as a linear array of bytes. There is no segmentation, and data objects are not limited to 64Kb as they are under Windows 3.1, without huge address compiler support. There are no far calls; any byte in the logical address space, whether code, data, or stack, can be addressed using a simple 32-bit offset.
