JPEG

  
   
a data file for pictures and photographs on the Internet. Full form Joint Photographic Experts Group


COMMENT: JPEG can either work through hardware or software routines and works as follows: the image is divided into a matrix of tiny pixels, every other pixel is ignored and the grid is divided into blocks of 8 × 8 pixels, the algorithm then calculates the average of the blocks and so can delete one block—the decompression is the reverse of this process.
