Answer :-

(i) Disk Defragmentor :-
A file is fragmented when it becomes too large for your computer to store in a single location on a disk. When this happens, your computer splits the file up and stores it in pieces. You can use fragmented files, but it takes your computer longer to access them.

Disk Defragmentor utility program speeds up disk access by rearranging the files and free space on your computer, so that files are stored in contiguous units and free space is consolidated in one contiguous block.

(ii) Backup Utility :-
This utility program facilitates the backing-up of disk. Back-up means duplicating the disk information so that in case of any damage or data-loss, this backed up data may be used.
