IMPORTANT FACT OF UNIT 1 FOR UGC NET


Information
·        Processed Data
·        First used in 1959
·        Derived from Latin word
·        The amount of information is measured in bits.
Example: Information in one "fair" coin flip: log2(2/1) = 1 bit, and in two fair coin flips is log2(4/1) = 2 bits.

Information Science

·        Science for managing and inventing information
·        Concern with analysis, collection, classification, manipulation, storage and dissemination of information
Information Society

·        Society which are more influenced with creation, distribution and manipulating the information and considering information as a prime source of development
·        The concept came in 1970 but it grows mainly in 1980 when some of scholars and writers encourage people that “what information can do for them!”
·        The first group of writers were “Masuda” in the Japanese context
Information as a Resource or Commodity

·        Information is used as a resource as well as commodity.
·        Information as a resource means using information to invent or generate some new knowledge.
·        Researchers are the largest user of information; they use information as a resource.
·        Information as a commodity means using information as a commodity like use of books, publication of information in books, serial or journals or others.
Communication

·        Came from latin word “communicare” which means “to share”
·        Means exchange of thoughts, messages or information between two persons by speech, writing, visuals, signal or behavior

Elements of Communication

·        Source
·        Encoder
·        Message
·        Communication channel
·        Noise
·        Decoder
·        Destination

Models of communication

Lasswell model of communication
·        Harold Lasswell developed this model in 1948
·        He was U.S. Political Scientist and communication theorist.
·        His theory was based on “who – says what – in which channel – to whom – with what effects?”   

Shannon and Weaver communication Model
·        This model came in 1949 by two communication theorist Shannon and Weaver.
·        This model has been called the “mother of all models”
·        This model is also been criticized of being too mathematical (also called mathematical theory).
Gerbner model of communication

http://communicationtheory.org/wp-content/uploads/2012/08/gerbner-general-model-of-communication.jpg
·        This model was developed by Mr. George Gerbner in 1956.
(i) Perceptual Dimension:
This is simple to understand that if ‘E’ is a source of information and passes his information to ‘M’ then it’s not exact same information or knowledge ‘M’ is grabbing. It depends on the ability of ‘M’ that how he interprets that information and that is where the value of information is change according to the sense of understanding of ‘M’.

These 3 factors are involves between ‘E’ and ‘M’
·        Selection
·        Context
·        Availability
 (ii) Means and Controls dimension:
E2 is received information from M who is not the exact source of information so the information which is delivered by M is based on priority and understanding of M. In other words, the information is modified as per preferences of M. So, the control and effectiveness on information is very low.
Important Note:
Message at every level is altered or changed.
Example:
In case of news reporting, E can be any event that has happened and the reporter (M) selects a particular part of event (E1) that may be provide his channel higher TRP ratings or the news may boost the particular party which his channel supports. This SE2 is sent through a medium to the mass audience. Then the audience distributed the message (SE2) and he (M1) sends to his friends with his interpretation and the process continues.

Schramm Model of Communication


·        Wilbur Schramm developed this model of communication in 1954

This model is seems very natural and real act of communication
Encoder – Who send message
Decoder – Who receives message
Interpreter – Person (who received message) trying to understand (analyses, perceive) or interpret about message
Fact: Interpretation is goes on in this model of communication every time when a person receives or send message. This means only interpretation effects message every time and interpretation is depend on the knowledge and understanding of person
Semantic noise is a concept introduced here it occurs when sender and receiver apply different meaning to the same message. It happens mostly because of words and phrases for e.g. Technical Language, So certain words and phrases will cause you to deviate from the actual meaning of the communication.
Fact: When semantic noise takes place decoding and interpretation becomes difficult and people get deviated from the actual message.

Types of Communication:

·        Formal Communication: Printed Materials (Books, Printed Document, Report etc.)
·        Informal Communication: Audio- Visual Material, Non-Printed Materials, T.V., Radio etc.

Intellectual Property Right

Intellectual Property
·        A product or service which is created by mind or intellectual thought of a person such as invention or any artistic and literary work.
·        Therefore, these inventions must be protected to encourage the inventors.
·        This is where the concept of IPR comes into existence.
Patent
·        Exclusive right granted for inventor who invent some new knowledge
·        With this no one can use, sell, made a copy of his product without patent owner consent.
Copyright
·        Legal right for a person who create artistic and literary work unique in its scope.
·        Works covered under copyright range from books, music, painting, sculpture, films, computer programs, database, advertisements, maps and technical drawing
·        Two rights covered under copyright for holder:

·        Right given to the person or organization who creates some unique design
·        It may be 2D design or 3D.
·        This is very important because:
If any company creates a design of car or bike then, it is not case of producing one or two bikes. It requires lots of investment and after that if that company realized that their design steals by any other company. Then it may create a big problem for that company and it discourages the inventions in design also. So, with this right company can ensure its success with design without any fear of copying.
Geographical Indication
·        Sign that used on the product which tells about its relation or origin of any specific part of world.
·        It cannot protect the product from copying but it protects only the sign of that product which recognized its origin.

·        After that Copyright act 1911 prevails until independence of India
·        After independence, new copyright act 1957 introduced on 1958.
·        And till now it is amended several times.
·        The latest amendment is done in 1994 which came in May 1995. 

Fact
