ISO files?

What is an ISO and how do i use it?

It is an image file that most likely came from a disk.

To use it, you can either extract all the contents from it with a program such as ISObuster, or mount it and just burn it onto a disc, depending on the size, it could be on a CD or DVD.
 
An iso image is the main means of downloading Linux distributions for write to disk followed by the installation onto your system. Think of a hard drive with Windows being packed into a zip file and opened on another drive later or burned to a cd or dvd where it runs when you boot from the removable disk(cd/dvd).

Large Linux distros will take 4 or 5 cd-rs if not 1 or 2 dvd-rs each with a separate iso burned to those. Recovery disks for prebuilt systems that are lost are often replaced by downloading the iso images for creating the needed disks to reinstall the recovery partition on the hard drive. I am presently trying to install Zenwalker a new Linux distro from an iso image. If ISOBuster is a freeware that will help.

Guess what? they redirected the free download link to http://www.download.com/3001-2248_4-10559872.html?idl=n

iso files are image...
it means that you can do an image of your HD and you have in one file all your files...
it is used much for pirate games on the net...
to open iso files, you have to have a specific program like daemon tools, alchol 120% or ISo buster, etc...
 
You can also burn ISO files to CD's or DVD's using Neros image burn feature within Nero.
 
At present I'm working with several iso images burned to disk to get a free Linux distro installed from an iso image burned to a cd-r. The full definition of just what is an iso9660 type image is described at http://en.wikipedia.org/wiki/ISO_image as follows:

ISO imageFile extension:.isoType of format:Disk imageAn ISO image (.iso) is an informal term for a disk image of an ISO 9660 file system. More loosely, it refers to any optical disk image, even a UDF image.
As is typical for disk images, in addition to the data files that are contained in the ISO image, it also contains all the filesystem metadata (boot code, structures, and attributes). All of this information is contained in a single file. These properties make it an attractive alternative to physical media for the distribution of software that requires this additional information as it is simple to retrieve over the Internet.
Some of the common uses include the distribution of operating systems, such as Linux or BSD systems, and LiveCDs.
Most CD/DVD authoring utilities can deal with ISO images: Producing them either by copying the data from existing media or generating new ones from existing files, or using them to create a copy on physical media.
Most operating systems (including Mac OS, BSD, Linux, and Windows, with third-party tools) allow these images to be mounted as if they were physical disks, making them somewhat useful as a universal archive format.
Console emulators, such as ePSXe, and many other emulators that read from CD/DVD, are able to run ISO/BIN (and other similar formats) instead of running directly from the CD drive. Better performance is achieved by running an ISO since there is no waiting for the drive to be ready and the hard drive I/O speed is many times faster than the CD/DVD drive.
A copy of CD contents, stored as an .iso file, is made this way: the ripper searches for the sectors of the CD that have been used, say 251,000 for instance (there are 330,000 sectors on a 74 min CD and 360,000 sectors on an 80 min CD). Each sector is copied to the .ISO file, one by one. For CDs each sector is 2048 bytes, the .ISO file should then be of size 251,000 x 2048 = 514,408,000 bytes.
Nero .NRG files are .ISO files plus a small file header.
