     1.5  Electronic communication is ``communication by computer'', according to the \name{WordNet} database of \name{Princeton University} \citeweb{wordnet}. Mobile phones and fax machines should be seen as computers here too. The \name{Science Glossary} of the \name{Pennsylvania Department of Education} describes electronic communication as ``System for the transmission of information using electronic technology (e.g., digital cameras, cellular telephones, Internet, television, fiber optics).'' \citeweb{science-glossary-pa}.

     1.7 -Electronic communication needs no transport of tangible things, only electrons, photons, or radio waves need to be transmitted. Thus electronic communication is fast in general. With costs mainly for infrastructure and very low costs for data transmission, electronic communication is also cheap communication. As underlying transport infrastructure, primary the Internet is used; thus electronic communication is available nearly everywhere around the world. These properties---fast, cheap, available---make electronic communication well suited for long distance communication.

The first dimensions regarded is the life time of the subject. It is segmented into the introduction, growth, mature, saturation, and decline phases. The second dimension can display market share, importance, or similar values. The graph has always an S-line shape, with a slow start, a rapidly increasing first half, the highest level in the fourth phase, and a slowly declining end. Reaching the end of the life cycle means, the subject gets inherited by successors or the market situation changed thus it is old fashioned.

    1.44  Provider independence through running an own mail server at home asks for easy configuration of the \MTA. Providers have specialists to configure the systems, but ordinary people do not. Solutions are either having some home service system for computer configuration established with specialists coming to ones home to set up the systems; like it is already common for problems with the power and water supply systems. Or configuration needs to be easy and fool-prove, to be done by the owner himself. The latter solution depends on standardized parts that fit together seamlessly. The technology must not be a problem itself. Only settings custom to the users environment should be left open for him to set. This of course needs to be doable using a simple configuration interface like a web interface. Non-technical educated users should be able to configure the system.
