Question

Which statement is NOT CORRECT?

Answer 1

Option C is not correct because in file system there is problem of using same data at different place with old and new updated versions and thus change in the data on one file is not reflected on the other related files implicitly rather we will have to change the data in each file manually which is indeed not easy task. In fact that is one of the biggest drawback of file system.

Option A is correct because the files of different data has separate definitions of the topics they are about.

Option B is correct because has no reversibility and thus same data can be present on different files.

Option D is correct because because of no reversibility the files can have same records with new or old versions
