The Free On-line Dictionary of Computing (30 December 2018):

delete
erase

   1.  (Or "erase") To make a file
   inaccessible.

   Usually this operation only deletes information from the
   tables the file system uses to locate named files; the
   file's contents still exist on disk and can sometimes be
   recovered by scanning the whole disk for strings which are
   known to have been in the file.  Files created subsequently on
   the same disk are quite likely to reuse the same blocks and
   thus overwrite the deleted file's data permanently.

   2.  The control character with ASCII code 127.
   Usually entering this character from the keyboard deletes the
   last character typed from the input buffer.  Sadly there is
   great confusion between operating systems and keyboard
   manufacturers as to whether this function should be assigned
   to the delete or backspace key/character.

   The choice of code 127 (binary 1111111) is not arbitrary but
   dates back to the use of paper tape for input.  The delete
   key rewound the tape by one character and punched out all
   seven holes, thus obliterating whatever character was there
   before.  The tape reading software ignored any delete
   characters in the input.
