What is an ISO Image?
An ISO image is a digital representation of an entire optical disc, such as a CD or DVD. It's basically a compressed file containing all the data that's written on a physical disc, including its file structure and content. This file is usually stored with a ".iso" extension, and you can think of it like a blueprint for creating an exact copy of the disc.
