If I burn a DVD data disk, can the CD be read from a standard CD-ROM Drive?

Thanks for your replies

No, a CD-ROM can't read DVDs.

You can download DVD-player software.

...and it still won't work on a CD player, like Zevia said.

CD-ROM: Reads CD-R, CD-RW, CD-ROM
DVD-ROM: Reads CD-R, CD-RW, CD-ROM, DVDR, DVDRW, DVD-ROM
COMBO: CD-R, CD-RW, CD-ROM, DVDR, DVDRW, DVD-ROM, Writes: CD-R, CD-RW
CD-Recorder: Reads CD-R, CD-RW, CD-ROM, Writes: CD-R, CD-RW
DVD-Recorder: Reads CD-R, CD-RW, CD-ROM, DVDR, DVDRW, DVD-ROM, (DVD-RAM sometimes), Writes: CD-R, CD-RW, DVDR, DVDRW (DVD-RAM sometimes)

Sometimes certain drives can read less (e.g. a DVD-ROM that cannot read DVDR media) but never more. But most of you already know this of course

well thank you all for your time and replies. The main thing that I was concerned about was if someday I don't have at least a dvd-rom drive, I won't beable to get my files. Guess I'll have to deal with it then.

Thanks again everyone
