In addition to this being incorrect, as Ken and Richard (so far) have pointed out, this isn't the distinction you are looking for.
All file formats contain data which is relevant to that file format. Zip files, executables, JPEGs, MP4s, all contain specific data structured in a specific way. If any of them has that structure interrupted by random bytes, the format has been broken and the file is corrupt.
It is no different for text data, which is expected to contain certain bytes and is normally not expected to be interrupted by a series of ranëH‰UÀHƒÈÿH
Does that help?
