Why is 32 bit x86?

The x86 moniker comes from the 32bit instruction set. So all x86 processors (without a leading 80 ) run the same 32 bit instruction set (and hence are all compatible). So x86 has become a defacto name for that set (and hence 32 bit). AMD's original 64 bit extension on the x86 set was called AMD64 .

In this regard, what is the x86 program files folder?

The regular Program Files folder holds 64-bit applications, while "Program Files (x86)" is used for 32-bit applications. Installing a 32-bit application in a PC with a 64-bit Windows automatically gets directed to Program Files (x86).

What are x86 programs?

x86-64 and IA-64 versions of Windows have two folders for application files: The Program Files folder serves as the default installation target for 64-bit programs, while the Program Files (x86) folder is the default installation target for 32-bit programs that need WoW64 emulation layer.

What is x86 mean?

It originally came from Windows XP. The first 64 bit edition of Windows was given the title Windows XP x64 . And I guess the term x64 stuck from there. The x86 moniker comes from the 32bit instruction set. So all x86 processors (without a leading 80 ) run the same 32 bit instruction set (and hence are all compatible).
