386 enhanced mode:A mode in Windows that runs on the 80386 and 80486 processors. It provides access to extended memory and the ability to run non-Windows applications. This and standard mode are both referred to as protected mode in Windows and offer more capability than Windows real mode.

8086 family of processors:All processors in the Intel 8086 family, including the 8086, 80286, 80386, and 80486 CPU chips.

8087 family of math processors:All math processors (also called math coprocessors) in the Intel 8087 family, including the 8087, 80287, and 80387 chips. These processors perform high-speed floating-point and binary-coded-decimal number processing. The 80486 chip includes a math processor.

8087 window:The CodeView window in which the floating-point math processor's registers are displayed. This window remains empty until a math processor instruction is executed. If the program uses the Microsoft math processor emulator library, the contents of the emulated math processor's registers are displayed.
