+### Binary Native Targets
+
+Since Open Watcom can produce binaries for several operating systems, 
+each binary has been given a unique name to distinguish the native **Operating System** (OS) 
+and **Instruction Set Architecture** (ISA) it is intended for.  
+
+| Binary Name   | Native OS       | Native ISA |
+|---------------|-----------------|------------|
+| **LUA16.EXE** | Real mode DOS   | 8086       |
+| **LUA4G.EXE** | DOS4GW extender | 80386      |
+| **LUANT.EXE** | Windows 95      | 80386      |
