In computing, Windows on Windows (commonly referred to as WOW) [1] [2] [3] is a discontinued compatibility layer of 32-bit versions of the Windows NT family of operating systems. Since 1993, with the release of Windows NT 3.1 , WoW extends NTVDM to provide limited support for running legacy 16-bit programs written for Windows 3.x or earlier.
In computing on Microsoft platforms, WoW64 (Windows 32-bit on Windows 64-bit) is a subsystem of the Windows operating system capable of running 32-bit applications on 64-bit Windows. [1] It is included in all 64-bit versions of Windows, except in Windows Server Server Core where it is an optional component, and Windows Nano Server where it is ...
After the mod was ported to StarCraft 2 and Dota 2, it was made into a paid standalone app using the Unity Engine for Android and iOS mobile devices in June 2016. [30] A second similar app was released on both platforms during mid-October, [31] [32] now available as free to download but with some content locked behind a paywall. [33]

A 32-bit register can store 2 32 different values. The range of integer values that can be stored in 32 bits depends on the integer representation used. With the two most common representations, the range is 0 through 4,294,967,295 (2 32 − 1) for representation as an binary number, and −2,147,483,648 (−2 31) through 2,147,483,647 (2 31 − 1) for representation as two's complement.
Beginning with Linux kernel version 4.1 released in early 2015, Linux on IBM Z is only available as a 64-bit operating system compatible with z/Architecture mainframes. Previously, Linux on IBM Z was also available as a 32-bit operating system, with 31-bit addressing, compatible with older model mainframes introduced prior to 2000's z900 model ...
An x86-64 processor acts identically to an IA-32 processor when running in real mode or protected mode, which are supported modes when the processor is not in long mode.. A bit in the CPUID extended attributes field informs programs in real or protected modes if the processor can go to long mode, which allows a program to detect an x86-64 processor.
DOS/32 has been commercially available since 1996. As of May 2002, it was released to the public in the form of "Liberty Edition" along with its complete source code under terms similar to the Apache License of the time, [a] allowing unrestricted, royalty-free distribution with certain provisions regarding reference to it in documentation and the naming of derived software.
