Definition
Multipurpose Internet Mail Extensions (MIME) is an Internet standard that enhances the format of email by allowing the inclusion of text in character sets other than ASCII, as well as attachments like audio, video, images, and application programs. MIME was designed to overcome the limitations of email, which was originally plain-text only, to facilitate more complex communication.
Examples
- Email Attachments: Sending a photo (JPEG) or a document (PDF) as an attachment in an email.
- Multilingual Emails: Emails containing text in multiple languages with different character sets (e.g., English and Chinese).
- HTML Emails: Sending emails with HTML content that can display formatted text, images, and links.
