What is an ISO File?
The term "ISO" is inherited from the file system's name commonly used by optical media, known as ISO 1960. We can understand ISO image or ISO file as a complete copy (or clone) of each and everything stored on a physical optical disc like CD, DVD, Blu-ray disc. In this type of optical discs, data is stored in the sector by sector manner, and it also does not use any data compression. The primary idea of creating an ISO image was so that the user could easily create an exact clone of the disc, and that image could later be used to burn a new disc as well. As a result, the newly burned image can be considered as the exact copy of the original and also behaves just like the original.
However, nowadays, almost all operating systems and many utilities allow you to mount an ISO image as a virtual disc. Therefore, all of your apps and computer systems treat it the same way they do when a real optical disc was inserted.
Nowadays, many people use ISO images to create backups of their optical discs. Although, the ISO images are primarily used to distribute the operating systems and large programs as it allows to convert all the content in one handy downloadable file. Now it's up to you to decide whether you want to mount that image or want to use it to burn a new disc. In general several downloadable operating systems like windows, Linux are distributed in the form of ISO images.
