What does communication theory deal with? What are those theories of mass communication which are relating to the concerns of users? Discuss the various hierarchies of media effects. Mass communication is part skill, part art, and part science. It is a skill in the sense that it involves certain fundamental learnable techniques such as focusing a television camera, operating a tape recorder, and taking notes during an interview. It is an art in the sense that it involves creative challenges such as writing a script for a television documentary, developing a pleasing and eye-catching layout for a magazine advertisement, and coming up with a catchy, hard-hitting lead for a news story. It is a science in the sense that certain verifiable principles involved in making communication work can be used to achieve specific goals more effectively. Many people want to pigeonhole mass communication as involving one or two of […]

Communication satellite

Communications satellite is an artificial satellite stationed in space for the purpose of telecommunications. Modern communications satellites use a variety of orbits including geostationary orbits, Molniya orbits, other elliptical orbits and low (polar and non-polar) Earth orbits. For fixed (point-to-point) services, communications satellites provide a microwave radio relay technology complementary to that of communication cables. They are also used for mobile applications such as communications to ships, vehicles, planes and hand-held terminals, and for TV and radio broadcasting, for which application of other technologies, such as cable television, is impractical or impossible A satellite in a geostationary orbit appears to be in a fixed position to an earth-based observer. A geostationary satellite revolves around the earth at the same angular velocity of the earth itself, 360 degrees every 24 hours in an equatorial orbit, and therefore it seems to be in a fixed position over the equator. The launch of […]

Various Forms of Feedback in Mass Communication

April 12, 2012 No Comments

Feed back In its simplest form the feedback principle means that a behavior is tested with reference to its result and success or failure of this result influences the future behavior Though not exactly cut-out for human communication, the Shannon-Weaver model provides clear guidelines for researchers to mark more avenues for graphic presentation of the elements in daily human communication. Forms of feed back There are five main categories of feedback. They are listed in the order in which they occur most frequently in daily conversations. 1. Evaluation Making a judgment about the worth, goodness, or appropriateness of the sender’s statement. 2. Interpretation Paraphrasing – attempting to explain what the sender’s statement means. 3. Support Attempting to assist or support the sender. 4. Probing Attempting to gain additional information, continue the discussion, or clarify a point. 5. Understanding Attempting to discover completely what the sender means by his/her statement. Role […]
