GIF files are used for screen presentation (72dpi) not for print applications.

You can store several GIF images in one file and exchange them at specified time intervals. These changes make it look like an animated file.

GIF should only be used on the Internet if the image only requires 256 colors. Images that have more than 256 colors should be saved as JPEG.

JPEG or JPG Joint Photographic Experts Group a raster graphics format which compresses an image to save space for DOS, Windows, Macintosh and UNIX.
JPG has a highly efficient way of compressing images and is used for large photos. (Images with a maximum of 256 colors should be stored as GIF, which have a more efficient way of compressing these images.)
JPG compression will reduce file size by about 5 to 20 percent.
MIDI Musical Instrument Digital Interface
Computers with a MIDI interface can record sounds created by a synthesizer and then manipulate the data to create new sounds. A variety of programs are available for composing and editing music conforming to the MIDI standard.
MIME Multipurpose Internet Mail Extensions A protocol that enables you to include various types of files as an attachment to an e-mail message.
