difference between cd rom and optical drive
Difference Between CDR and CD ROM. CDR (CD-R) and CD ROM are two classifications of compact discs that are used to store data either, documents, audios, movies, or any other types of media formats that can be played through cd/dvd player or a computer cd/dvd rom drive. The standard size of CDR and CD ROM is 700MB.
Optical drives retrieve and/or store data on optical discs like CDs, DVDs, and BDs (Blu-ray discs), any of which hold much more information than previously available portable media options like the floppy disk. The optical drive normally goes by other names like a disc drive, ODD (abbreviation), CD drive, DVD drive, or BD drive.
