Comparing the designs of Windows 3.1, Windows 95, OS/2 Warp Connect, and Windo
ws NT 3.51
All four OSes run 16-bit Windows applications. All four can run 32-bit applications (albeit not necessarily the same ones). But they each have different ways to ensure that the applications run. The Windows 3.1 architecture is probably the easiest to crash; Windows NT's architecture is probably the most secure. Here's why.
Windows 3.1
Under Windows 3.1, there is one System VM. When you look at the memory map, you can see what that means: All applications run in the same address space. In addition, the DLLs that provide OS services run in this same memory space. With this architecture, if one application crashes, it's likely that all of Windows will crash.

theoretical--and no language better exemplifies this than C++.
