Communications
Communication is the activity of conveying meaningful information . Communication requires a sender, a message, and an intended recipient, although the receiver need not be present or aware of the sender's intent to communicate at the time of communication; thus communication can occur across vast distances in time and space. Communication requires that the communicating parties share an area of communicative commonality. The communication process is complete once the receiver has understood the sender.
Human communication: Human spoken and picture languages can be described as a system of symbols and the grammars ( rules ) by which the symbols are manipulated.
Nonverbal communication: Nonverbal communication describes the process of conveying meaning in the form of non-word messages. Research shows that the majority of our communication is non verbal, also known as body language. some of non verbal communication includes gesture , body language or posture ; facial expression and eye contact, object communication such as clothing , hairstyles , architecture , symbols info graphics , and tone of voice as well as through an aggregate of the above. Non-verbal communication is also called silent language and plays a key role in human day to day life from employment relations to romantic engagements.
Visual communication: Visual communication is the conveyance of ideas and information through creation of visual representations. Primarily associated with two dimensional images, it includes: signs , typography , drawing , graphic design , illustration , colors, and electronic resources, video and TV. Recent research in the field has focused on web design and graphically oriented usability. Graphic designers use methods of visual communication in their professional practice.
Oral communication: Oral communication , while primarily referring to spoken verbal communication, typically relies on both words, visual aids and non-verbal elements to support the conveyance of the meaning. Oral communication includes discussion, speeches, presentations, interpersonal communication and many other varieties. In face to face communication the language and voice tonality plays a significant role and may have a greater impact on the listener than the intended content of the spoken words.
Written communication: During the 1st stage written communication first emerged through the use of pictographs. The pictograms were made in stone, hence written communication was not yet mobile.
During the 2nd stage writing began to appear on paper, papyrus, clay, wax, etc. Common alphabets were introduced and allowed for the uniformity of language across large distances.
The 3rd stage is characterized by the transfer of information through controlled waves and electronic signals.
Nonhuman communication: Every information exchange between living organisms - i.e. transmission of signals that involve a living sender and receiver can be considered a form of communication; and even primitive creatures such as corals are competent to communicate. Nonhuman communication also include cell signaling , cellular communication , and chemical transmissions between primitive organisms like bacteria and within the plant and fungal kingdoms.
Animal communication: Animal communication can be defined as any behavior of one animal that affects the current or future behavior of another animal. The study of animal communication, called zoosemiotics'.
