OT - What is ISO, anyway? Why use it?

  • Thread starter Thread starter Helen

Perhaps it could be thought of as a process... by analogy, it's an image (as in a
photo of you, isn't YOU
but merely an image (something similar) to you). It's not a copy... it's a
likeness... it can get techincal.

"What are ISO image files and how do I use them?

Many products are posted as ISO-9660 image files. An ISO-9660 image
file is an exact representation of a CD, including the content and the
logical format. The most common use of an image file is to write it to
a blank CD-R resulting in an identical copy of the original CD
including file name and volume label information. ISO image files may
also be opened and their contents copied to a local folder, much like
ZIP files. ISO files may also be virtually mounted and accessed as a
CD-ROM device."

I wondered what an ISO image is as well; this helps, many thanks.

Helen writes that this is not a copy, but it sure sounds like a copy, even if an ISO file has other capabilities.
"...an exact representation..." would pass as a copy in my estimation. The ISO image file contains much more info
than a photograph.The analogy of a picture not being an actual person seems not applicable. :-)
An ISO file seems roughly similar to the data backup of a drive.

a copy would be a duplication of the files, but not necessarily the format
of the original medium...an iso also dupes the format of the original
medium...floppy, cd, etc. you could make a copy of a floppy onto a cd, but
the sector format of the cd is still different from that of the floppy.

Because of copy-rhats...terminology is imperative. Whatever term you need to help you
get what you want... to do what you want... depending on the program used to 'grab the
ISO'..
it can be made bootable, or not. If it helps you to think of it as kinda-sorta like
backup... then OK, but you know you aren't copying illegal disks.... if you get my
drift! Some
people get wrapped around the axle with the term 'copy'. Seemingly they immediately
attribute some illegal activity to that term... .. but it is a process... the
letters stand for
Internat'l Standardization ...
think of it as similar to ascii except not for simple text only.
 
OK, I think I understand too. Almost. I think. Maybe.

If I can copy every thing on a CD to my hard drive or copy it to another CD,
then I assume every thing is transferred.

Now as I understand this, it may be different. If everything is there and
readable, why would I care if the format is different??????

Copy-rhats is a new term to me, a good one. :-) Tactfully and very well explained, Helen. Thanks. I was dreading a
flaming.
"Copy" was such a bad bad term in the good old days of copy protection and programs like 21 Second Backup, Fast
Hack'em, Di-Sector and other fun programs; I though it had lost its negative connotations. Guess not.

But the method used to store data doesn't matter, in realistic terms, as long as I have the CD info/image.
Helen thinks that "Copy-rhaters" may not like it, though. :-)

because the file is a lot smaller than a zip or rar file, this how someone
explained iso to me,imagine i create a image[photo] of a apple using a iso
program,then i send the image to you and then you use a iso program to convert
the image of the apple back into a real apple!.
 
it's not necessarily the fact that a piece is copyrighted that is the key
focus...it's what permissions the copyright owner/holder allows others to
excercise.
