acronym for "In My Humble Opinion" mostly used in e-mail messages.

a psuedo-Teutonic synonym for Information Superhighway (taken from Autobahn, the German highway system), commonly used because it's shorter and "cooler" than Information Superhighway.

Information Superhighway
the near-mythical agglomeration of the Internet, communications companies, telephone systems, and other communications media that politicians seem to believe will be the "next big thing" in business, academia, and industry. Many people believe that this highway is already here, and that it's called "the Internet."

input-handling program

IP is the specific networking protocol of the same name used to tie computers together over the Internet; IP is also used as a synonym for the whole TCP/IP protocol suite.

ISDN (Integrated Services Digital Network)
an emerging digital technology for telecommunications that offers higher bandwidth and better signal quality than old-fashioned analog telephone lines. Not yet available in many parts of the US or in the rest of the world.

the granddaddy of standards organizations worldwide, the ISO is a body made of standards bodies from countries all over the place. Most important communications and computing standards -- like the telecommunications and character code standards mentioned in this book -- are the subject of ISO standards.
