    32bit or 64bit?

    I have Ubuntu 10.04 LTS installed...how can I find out if I have 32bit or 64bit version?

    Also, can someone briefly explain why there is this importance about "do you have 32bit or 64bit"?! ie. what does it mean?!

    You should be able to run uname -a in a console or terminal to see what you are running:

    Code:
    uname -a
    For example, here's mine running Arch Linux:

    Code:
    $ uname -a
Linux compuser 2.6.39-ARCH #1 SMP PREEMPT Mon Jun 27 21:26:22 CEST 2011 x86_64 Intel(R) Core(TM) i7 CPU 950 @ 3.07GHz GenuineIntel GNU/Linux
    The part about x86_64 shows that I'm running the 64-bit kernel.


    You can read up on the different architectures here:

    Check other sections of the article for additional info.
