in s/ws used for burning CDs, what is the term creating image file?

[m_abdelghani]

hey all.
I hope I am posting this in the right place
when I burn CDs there is an option of creating image file for the data I will burn on CD
I've tried to read the accompanied tutorial with burning S/W where I concluded that creating image file means theat all data to be burnt are represented as one image and to be recordedas that form on CD .. is this true?
and If so how it can be.. is it a real image or the term image means here a copy
sorry for my questions but I really need to know that
thanks in advance

Depends on the software.

An exact copy can be called may things.
An Image or ISO is common.
