The most common form of communication is the transfer of information from person to person.
Communication can also take place between person and creature or mechanism and p erson.
This information transfer manifests its self in many forms like speech, text, diagrams, graphs, etc. With such a wide range of communication media and participants, the possible communication arrangements are staggering. Scientific communication systems have evolved out of necessity to deal with the ever increasing amount of information. This glut of information is a result of technological advances in collecting scientific data. Automated collectors make it possible for data to be collected with less and less effort by the scientific personnel.
