About MIME types
A MIME type (Multipurpose Internet Mail Extensions type, now officially called an Internet Media Type) is a two-part identifier — type/subtype — that tells software what kind of content it's about to handle. Browsers use the Content-Type response header to decide whether to render HTML, play audio, download a file, or display an image.
