What does ISO mean?
An ISO image is an archive file (a.k.a. disk image) of an optical disc using a conventional ISO (International Organization for Standardization) format that is supported by many software vendors. ISO image files typically have a file extension of .ISO but Mac OS X ISO images often have the extension “.CDR”. The name “ISO” is taken from the ISO 9660 file system used with CD-ROM media but the term ISO image can refer to any optical disc image, even a UDF image. You really don’t need to know what it means too much because if for example you are using a PSP with Custom Firmware, all you do is make a folder on the Root folder(the folder when you first hook your PSP to your computer via USB, and once it asks you a bunch of tasks to do.. just click ‘Open folder to view files’ then make a folder called ‘ISO’ without the appostrophes and drop your game into there. I know that really wouldn’t be your scenario if you don’t have a PSP, but, if you do and was wondering how to put ISO games onto you
ISO stands for International Service Office and is the central office for Gamblers Anonymous. It handles items such as official literature, and new group meeting starter kits, as well as any issues involving Gamblers Anonymous as a whole. In other countries, an RSO (Regional Service Office) may handle such issues.
