Answer Posted / ankit singh
1. When we open a file stored on a disk, its logical file is
created and we work on that file.
2. Once we save the file, the changes we made are reflected
in the physical file. If we don't save the file, the
physical file doesn't get affected.
3. When we close the file, the logical file which was
created on opening the file, gets destroyed.
