A measure of data storage equivilent to roughly one million chracters of text. Abbreviation: Mb.

Your account with 20/20 Technologies will have four megabytes of storage, which should be more than enough for even a very large Web site.

High resolution color images are the largest use of storage, with large images taking up as much as a one-half Mb. We suggest that images on the World Wide Web be no larger than one-tenth Mb, since users do not appreciate the downloading times associated with larger images.
