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

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