How to check Operating system(Windows and Ubuntu) is 32- bit or 64-bit?


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.

or

ia64 ia64  ia64  GNU/Linux instead  of  i686 i686 i386 GNU/Linux.

Note: uname -a  command returns all system information of ur Ubuntu OS. To know more about this command use ‘uname – -help’ in the command line.

That’s all…!!!!

Enjoy..:):)
