Whenever you trying  to download  Google video chat, adobe flash player, Labview..You will be asked about the Operating system you want to install for i.e. 32-bit or 64-bit.
32-bit /64-bit says to what your softwares are compiled to..!!!
You can check your OS is 32-bit/64-bit. It’s easy.:)

Windows Xp:
Right click on My Computer–> Properties
if you are using Windows7: 
go to Start–> System   (Type system in search box in starte menu if you are not able to find System)
Now click on system and you get all the information about your system.Simple..:)

If you are Ubuntu user:
go to Terminal and type the command:
  uname -a
If it is 32-bit Ubuntu Operating system you get this:
Linux ubuntu 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:50 UTC 2011 i686 i686 i386 GNU/Linux
Note: I am using Ubuntu11.04. this is the message I got..
If you are using 64-bit:
You get a message as above but with x86_64 x86_64  x86_64 GNU/Linux instead  of  i686 i686 i386 GNU/Linux.
ia64 ia64  ia64  GNU/Linux instead  of  i686 i686 i386 GNU/Linux.
