J
JBIG
Joint Bi-level Image Experts Group. An experts group file specification that defines a
standard for compressing (reducing the size of) image files without any loss in image
information. Files containing photographic images in Web pages are generally
compressed so they can be transferred across the Internet more quickly. JPEG, the
format currently used, causes some loss in image data after compression, and so
reduces image quality. JBIG compression overcomes this shortcoming.
JPEG
Joint Photographic Experts Group. An experts group file specification that defines a
standard for compressing (reducing the size of) photographic and photorealistic
image files. The image compression method used involves some loss of information,
and so reduces image quality. Files containing photographic images in Web pages
are generally compressed by using the JPEG format so they can be transferred
across the Internet more quickly.

devices, and computers, which are all located in the same building or some other

telephone company if you experience difficulty in long distance dialing.
