Iso?


I'm like poltergiest, "I'm Back", I was searching for started threads on the ISO image and for once in a forum I find how to's, what is an ISO? What is its function? Will an operating system work without it or is only like a perk?
Thank you and good to be back Saquear!!!

Kinda` like a tutorial about creating and using ISO's is found here:
http://iso.eng.frendz.ch/
In plain english, an ISO image is the "image" of a cd that is ready to burn. (ex. you don't need to add the files to the compilation yourself)

It's also possible to mount ISO images without first burning them to the disk. You would mount it just like a CDROM, but instead of /dev/cdrom (or whatever) you'd use the name of the ISO image in your mount command:

Code:
mount -t iso9660 file.iso /mnt/mountpoint -o ro
should do the trick.

ISO is an acronym for International Organization for Standardization www.iso.org. The info on their webstite explains what standards are about.

The standard for how data is written on a CDROM is ISO 9660. Hence the filesystem is called iso9660 and an ISO file is just an exact byte for byte image of a CD.

An ISO is necessary only if you something to do with it
Storing an ISO makes it easyer to gather the files you need to burn ito a CD. It also keeps the files together for further burning.

Since an ISO file is an exact image of the CD it also contains the boot loader. So it really is only necessary for bootable CDs. BTW bootable CDs confirm to the El Torito format.
