Incidentally your CD is really referred to CD-ROM... which translates as Compact Disc - Read Only Memory. Of course some are the equivalent of PROM... those would be CD-R, while others are equivalent to EPROM... the CD R/W.

You fingers are writing checks your knowledge can not cash

EPROM's are not equivalent to CD-R/W (similar but not equivalent). You can not Read/Write to an EPROM. An EPROM can only be erased in totality. E = erasable.

Thank you for pointing that a CD is actually a CDROM meaning it is read-only memory and what makes software firmware - say it with me - "when it is stored in read-only memory".

HINT: EEPROMS are equivalent to CR-R/W

You are the one who has been using loose analogies... do you not understand the concept?
