media type

Definition

A Media type (formerly known as MIME type) is a standard way to indicate the nature and format of a file, like 'image/jpeg' for JPEG images, used on the internet.

It is a two-part identifier for file formats and format contents transmitted on the internet. Their purpose is somewhat similar to file extensions in that they identify the intended data format.

The Internet Assigned Numbers Authority (IANA) is the official authority for the standardization and publication of these classifications.
