Instead of storing data in plain text, they store it in the binary form (0's and 1's).

They can hold higher amount of data, are not readable easily and provides a better security than text files.

A file represents a sequence of bytes on the disk where a group of related data is stored. C programming language can handle files as Stream-oriented data (Text) files and System oriented data Binary) files.

The result is that no meaningful output occurs (probably) and this is to be expected.

A file is simply a machine decipherable storage media where programs and data are stored for machine usage.

The first four operations listed above are for both text and random access files. Random access means you can move to any part of a file and read or write data from it without having to read through the entire file.

Years ago, data was stored on large reels of computer tape.

Abstractly, a file is a collection of bytes stored on a secondary storage device, which is generally a disk of some kind.
