If so, what would that mean?
I do not understand your question.
If there's a drive, then a CD fits in too.
I might want to buy a laptop notebook, but there are so many names I'm looking for a laptop in the CDs fit but when I enter drive I will not see anything
CD is only the round disc.
If a drive is installed, fits one in. But not every drive can read every CD (this will depend on the format, as the CD is coded on it (DVD, CD-ROM, Blueray, etc.).
Then it might be useful to know where you want to pick that.
DVD Rom / DVD RW would be an approach. Or optical drive.
If in doubt, you look at the picture.
A CD can read any drive, DVD drives are now almost always installed. Only with a BluRay it will be hard.
There's no specific name if a part has a drive or not. So you have to look in the technical data of an offer, whether CD or DVD read udn if necessary also CD or DVD can be burned. A blueray drive is rather rare to find on notebooks.
I do not suppose that the gentleman here wants to play Blueray on it.
Properly a "CD" can read any drive.
A CD-R, CD + R, CD-RW or CD + RW on the other hand… Let's say this: It would be expected that every drive can now read these blanks - I would not put my hand in the fire.
Conclusion: Specs study. What is not expedient in it does not have to be supplied by the manufacturer.
