Multipurpose Internet Mail Extensions (MIME) is an Internet standard that extends the format of email to support:

• Text in character sets other than ASCII
• Non-text attachments: audio, video, images, application programs etc.
• Message bodies with multiple parts
• Header information in non-ASCII character sets

A mime or mime artist (from Greek μῖμος, mimos, "imitator, actor") is someone who uses mime as a theatrical medium or as a performance art, involving miming, or the acting out a story through body motions, without use of speech. In earlier times, in English, such a performer would typically be referred to as a mummer. Miming is to be distinguished from silent comedy, in which the artist is a seamless character in a film or sketch.
