Disk I/O operations are performed on entities called files. The brief categorisation of Disk I/O functions is given below:-
From above we can see that the file I/o functions are further categorised in to text and binary.

(a) How new lines (\n) are stored
(b) How end of file is indicated
(c) How numbers are stored in the file
