Data Compression in Multimedia (Text,Image,Audio and Video)

? Multimedia files are large and consume lots of hard disk space. The files size makes it time-consuming to move them from place to place over school networks or to distribute over the Internet. ? Compression shrinks files, making them smaller and more practical to store and share. ? Compression works by removing repetitious or redundant information, effectively summarizing the contents of a file in a way that preserves as much of the original meaning as possible.
