How are disk images such as iso, img, and dmg written? For example, if I make a file with no extension with some text in it and put it in a disk image, how does it get incorporated, with what kind of parameters?

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form.

I am not seeing how your second question relates to the first. You will simply have a file, in the ISO archive, with no extension. You should work on refining the first question and discard the second. – iglvzx Feb 28 '12 at 2:14

As I understand it, an ISO file is composed of uncompressed files merged into a single file, with various attributes identifying the type of file system and potentially the physical medium.
