The Full Form of WROM is‍ Write once, read many.

Write once read many (WORM) describes a data storage device in which information, once written, cannot be modified. This write protection affords the assurance that the data cannot be tampered with once it is written to the device.

On ordinary (non-WORM) data storage devices, the number of times data can be modified is limited only by the lifespan of the device, as modification involves physical changes that may cause wear to the device. The “read many” aspect is unremarkable, as modern storage devices permit unlimited reading of data once written.

WORM protects the important files by keeping them safe and intact. It ensures the highest level of integrity and data security by eliminating the risk of important data from being deleted or modified. This way, the WORM helps to preserve the authenticity and safety of recorded data.

Write-Once, Read-Many (WORM) is a data storage technology mechanism that stores unerasable and/or unmodifiable information after it has been written on a drive. The data is stored on WORM devices. These device disks store data in a non-rewritable format to prevent users from accidentally erasing or altering sensitive information.

WORM is also known as Write Once, Run Anywhere (WORA).

Created in the late 1970s, a WORM device is a type of optical media commonly used for archiving information or hosting data archives. This useful data is written on a disk only once, which is useful because archive creators or gatekeepers typically seek information that has not been altered or modified from the original source.
