Again, you are wrong. A CD that contains data does not have to fit the definition of "firmware" unless its content is designed by a company to direct the operation of a piece of hardware the firm has built or designed.
You really don't understand much about computer technology and you do have problems with reading comprehension - notice I said "software on a CD" - not data.
All software directs the operations of hardware. Software does nothing without hardware and vice-versa (unless you include uses like paper weight)
Lets review a definition of firmware:
firmware: n : (computer science) coded instructions that are stored permanently in read-only memory (WordNet ® 2.0, © 2003 Princeton University)
Question: Is a CD (not a CD-RW) read-only permanent memory?
Answer: yes.
You always start with insults... I have been working in the computer industry for 26 years. I majored in Business Administration with minors in economics and pholosophy. I have an IQ of over 150... I do not have "problems with reading comprehension"... my problems is that I, like Petronsky, do comprehend what you write, but cannot see beyond your imprecision to what you really want to say.
EVERYTHING stored on media is data of some form or another... some data is used as instructions sets, some data is manipulated by those instruction sets, and some data is there for identification purposes and inaccessible to the device reading the other data. It is how that data is used that differentiates what kind of data it is. For example a medium might contain a Windows applications. That data can be read into the computer and executed to do something... or it might be read into an editor as data for revision... its data.
