DOC is the legacy binary format used by Microsoft Word before 2007. While still widely encountered, it has been superseded by DOCX. Many older documents and templates still use this format.

HyperText Markup Language

HTML is the standard markup language for creating web pages. While primarily a web technology, HTML files are also used as a portable document format with rich formatting and multimedia support.
