Communications Standard Dictionary

Book excerpt: Communications * Standard Dictionary is a comprehensive compilation of terms and definitions used in communications and related fields. Communications is defined as the branch of science and technology concerned with the process of representing, transferring, and interpreting the meaning as signed to data by and among persons, places, or machines. Communication is defined as the transfer of information between a source (trans mitter, light source) and a sink (receiver, photodetector) over one or more chan nels in accordance with a protocol, and in a manner suitable for interpretation or comprehension by the receiver; or as a method or means of conveying informa tion of any kind from one person or place to another. In short, communications is a branch of science and technology, whereas com munication pertains to the actual transfer of information. Thus, the word com munication should be used as a modifier, as in communication center, communi cation deception, and communication line, just as in the field of electronics one speaks of electronic devices and electronic circuits.
