How to find the architecture of OS installed
I'm using Core 2 Duo. From Intel website I found that it is a 64-bit architecture CPU.
Long back I've installed Ubuntu OS on this machine. But I'm not sure if I installed the x86-32 or x86-64 version of Linux. I want to know which version of Linux I'm using. How can I get to know that?
How do I find the same on Windows?
On Unix-like OSes you can type uname -m
to show the architecture:
$ uname -m
x86_64
Under Windows follow Microsoft's guide:
To find out if your computer is running a 32-bit or 64-bit version of Windows in Windows 7 or Windows Vista, do the following:
Open System by clicking the Start button, right-clicking Computer, and then clicking Properties.
Under System, you can view the system type.
If your computer is running Windows XP, do the following:
Click Start.
Right-click My Computer, and then click Properties.
If you don't see "x64 Edition" listed, then you're running the 32-bit version of Windows XP.
If "x64 Edition" is listed under System, you're running the 64-bit version of Windows XP.
On Windows Vista and newer you can run the command
wmic os get osarchitecture
to find out whether it's 32 or 64 bit.
