Basically an ISO is an exact copy of the contend of a CD/DVD-ROM in your hard drive and it's also called "image". ISO files does not only apply in games, but in programs too.

Most of the cases, ISOs are used commonly for emulation and if you are trying to get ISOs to work with your PSP, I have no idea. Maybe it's not possible.
