What is the difference between DVD-ROM and DVD Combo drives?

Based on the brands and models I previously encountered, DVD-ROM drive is a computer component that Plays pre-encoded movies and reads any DATA Written on a DVD-ROM Media and because it is on the higher ground than CD-ROM Drive, it can play movies and read DATA Written on a CD-ROM Media while on the other hand Combo Drives in general are drives that combine the DVD-ROM and CD-RW Drive’s functionality into one single drive. This drive will read and write data to a standard CD-ROM media and to add its ability, it has the DVD-ROM’s function as stated above. So to scale them up, combo drive is definitely on the higher ground.
