Binary files are a type of computer file that contains data in a format that is not human-readable. Unlike text files, which store data as plain text characters, binary files store information in a series of bytes. This allows them to represent complex data types, such as images, audio, and executable programs, more efficiently. Because binary files are not meant to be read directly by humans, they require specific software or programs to interpret their contents. For example, a JPEG image file or a MP3 audio file is stored in binary format, and applications like image viewers or media players are needed to open and display the data correctly.
