Once I was trying to install Docker for my project. I was looking at the documentation of docker and get to know that Docker is only works on 64 bit machine. I was running with Ubuntu 14.04 32 bit on my machine. And I was not sure that my hardwares will support 64 bit OS because my machine is quite old.
So I started searching on web with question “How I can know my hardware supports 64 bit OS ?” . After juggling in google I find that it depends on which processor model you are using.
Following are steps to know your processor supports 64 bit OS or not.
Note : All commands are tested on Ubuntu
Step 1 : Get processor information by command
less /proc/cpuinfo
This will give you information of processor.
Grab the Model name. In my case it is : Intel(R) Core(TM)2 Duo CPU T5670 @ 1.80GHz
Step 2 : Open Company website
For Intel : http://ark.intel.com/ or For AMD : http://products.amd.com/en-us > view details
Step 3 : Search of model number in website
In my case T5670
Step 4 : Search for field Intel 64 in website
If value is yes then it supported and if value is no then it is not supported.
After installing 64 bit OS into your machine, Verify OS by Following command :
uname -a
In my case result is like this :
Linux
Hope that helps!!!
