Processed "word" size.

Win16 processes 16 bit words while Win32 processes 32 bit words. In the very near future we will all be processing 64 bit words.

API's

by epepke In reply to what is win32 & win16

They are both API's (Application Program Interfaces). They are the stubs that a developer uses to create an interface with the operating system when the application is run to do things like bring up windows, read files, etc.

The win16 API was written way back when it seemed natural to use 16-bit integers to do a lot of things. Later on, as computers became bigger, the 16-bit limitation seemed restrictive, and so win32 was created. (The old notepad's limitation of characters was a result of win16 thinking.)

Most MS operating systems will run applications written with either. XP, it is claimed, will not run applications written with win16. I am not sure about Windows 2000.

I don't know of any way to tell, easily and automatically from a finished program whether it was written with win16 or win32, except to say that applications written in the past few years are probably win32, and very old applications are definitiely win16. The developer, of course, knows the difference because they are different libraries and header files.
