What Is an ISO Image?

An ISO image, also known as a disc image or copy of everything stored on a physical optical disc such as a CD, DVD, or Blu-ray. It is a sector-by-sector copy of the disk and no compression is used, making it a complete replica of the original data. The term 'ISO' comes from the name of the file system used by optical media, typically ISO 9660.

An ISO image is an archive file that contains a precise copy of the data found on an optical disc. It can be used to back up optical discs or distribute large sets of files intended to be burned onto an optical disc. In many cases, software companies supply their products in digital format, and sometimes they may require a backup copy of the disk.

When a situation arises where a copy of a disc needs to be saved, that's when an ISO image appears on the scene. This article will delve into what an ISO is and how to burn an ISO to DVD using popular burning programs.

What is 'anyburn buffer size'?

Before we explore the process of burning an ISO to DVD, it's essential to understand the concept of buffer size in disk imaging software like AnyBurn. The buffer size refers to the amount of data that can be temporarily stored in memory while reading or writing data to a physical disc.

A larger buffer size allows for faster data transfer and better performance, especially when dealing with large files. However, it also consumes more system resources and may lead to slower overall disk usage.

In summary, an ISO image is a sector-by-sector copy of everything stored on a physical optical disc, without compression, that contains the identical copy of the data found on the original disc. It's used for backing up or distributing large sets of files intended for burning onto an optical disc.
