Research is a human activity based on intellectual investigation and aimed at discovering, interpreting, and revising human knowledge on different aspects of the world. Research
can use the scientific method, but need not do so.

Communication is a process that allows beings - in particular humans -
to exchange information by several methods. Communication requires that some
kinds of symbols from a kind of language are exchanged. There are
auditory means, such as speaking or singing, and nonverbal, physical means, such as body language, sign language, paralanguage, touch or eye contact.

Communication happens at many levels (even for one single action), in many
different ways, and for all beings, and some machines. Many or all, fields of
study dedicate some attention to communication, so when speaking about
communication it is very important to be sure about what aspect of communication
one is speaking about. Some definitions are broad, recognizing that animals can
communicate with each other as well as human beings, and some are more narrow,
only including human beings within the parameters of human symbolic
interaction
