If you download iso file with ubuntu you will get something like this:

ubuntu-10.04.3-server-amd64.iso

ubuntu-11.10-desktop-amd64.iso

Every part in the file name is pretty clean to me, except 'amd'.
So I have the following questions.

Why is there the 'amd' string in the filename?

What other kind of strings in the filename can be found instead of 'amd'?

It's merely a convention due to the fact that AMD created the 64-bit extensions to the x86 (Intel 386/486/Pentium) instruction set. At that time, Intel was pushing Itanium as the only 64-bit solution, and Intel didn't copy AMD's extensions until it was clear that AMD had created something that was being used widely. The #define AMD64 was used to distingish this 64-bit instruction set from Intel's Itanium instruction set.
