MIME converts non-textual data into NVT-7 bit data and deliver to SMTP client in reviver side it will transfer back to original message. It also allow the user to sent audio, video data as well it also transfer them to NVT-7 bit automatically. Simply we can define that MIME is a specification for the non textual attachments. Which allows your web browser or email clients to send things like audio, video, spread sheet etc over the internet.
