Ans:- वर्म डिस्क Compact Disc-Recordable (CD-R) technology is known as Write Once-Read Many (WORM), which allows you to write data onto a disk just once that can not be erased. CD-R discs are blank CDs that can record data written by a CD burner. The abbreviation WORM stands for "write once, read many." A WORM file has the property that data can be written only once to any area of the file and can never be overwritten or erased before the retention period expires.
