ISOlevykuva

ISOlevykuva is a Finnish term that translates to "ISO image" or "disc image." It refers to a file that contains the complete contents of an optical disc, such as a CD or DVD, in a single file. This image file preserves the disc's file system structure, data, and boot information, making it an exact replica of the original disc. ISOlevykuva files are commonly used for software distribution, operating system installation media, and data archiving. They can be created using specialized software that reads the data from an optical disc and saves it into an ISO format.

To use an ISOlevykuva, it can be mounted as a virtual drive on a computer, allowing the operating system to access its contents as if a physical disc were inserted. Alternatively, the ISOlevykuva can be burned onto a blank optical disc using burning software, effectively recreating the original disc. This process makes it easy to back up important discs or to distribute software without the need for physical media. The ISO format is a widely adopted standard, ensuring compatibility across different operating systems and software applications.
