Sorry for such a simple question.
I want to install 64 bit ubuntu 12.04 on Intel PC.
At this link, http://releases.ubuntu.com/12.04/ various download links for ISO files are available.
I have a small confusion in the two links as shown below.
- ubuntu-12.04.4-desktop-i386.iso
- ubuntu-12.04.4-desktop-amd64.iso
Question 1 : Which one of this is a 32 bit OS and 64 bit OS ?
Question 2 : Is the second link only for AMD processor based CPU's ?
