    1- Information is built upon the basic concepts of ?
    *A\ data, models, system and information
    B\ data,information,system,programs
    C\ informatiom,systems,models,technology
    D\ technology,programs and system

    2- Data defind as :
    A\ collection of knowledge and it is elements
    *B\ collection of knowledge of facts
    C\ application of knowledge to facts
    D\ number and letters

    3- on of the following is not a feature of models:
    A\ models are always less detailed than the real world from which they are drawn
    B\ many models can be created of any given physical object, depending upon the level of detail and point of view selected
    C \ the similarity between models and the physical object they represent degrades over time
    *D\ there is a truly general purpose model

    4- the four maximum`s rules for conducting messages exchanges are :
    A\ Quantity,quality,efficiently and channel
    B\ Quantity,quality,efficiently and manner
    *C\ Quantity,quality,manner and relevance
    D\ Quantity,quality,relevance and channel

    5- (Messag class) Decide whether the message should be ( data oriented,task oriented or template orirnted)?
    we can never make the case that a specific message class is best for all messages

    6- what the difference between formal information system and informal information system?
    A\ a formal information system contains an agreed model for the interpretation of data, and data within the system are structred in accordance with that model

    B\ an informal information system is neutral to the interpretion of data, containing no model and imposing minimal structure on any data to allow it to be stored,retrieved and shared




    7- What are the two ways of creating models?

    Abstraction And Instantiation


    8-List two important features characteristic of all models.?

    1. Models are always less detailed than the real world from which they are drawn.
    2. Models ignore aspects of the world that are not considered essential. Thus abstraction imposes a point of view upon the observed world.
    3. Many models can be created of any given physical object, depending upon the level of detail and point of view selected.
    4. The similarity between models and the physical objects they represent degrades over time.
    5. There is no such thing as a truly general purpose model. There is no such thing as the most ?‘correct’ model. Models are simply better or worse suited to accomplishing a particular task. All models are built for a reason.

    9- characteristic of information systems?
    1. Systems have inputs and outputs
    2. Systems have behaviour
    3. Physical systems are embedded in an environment
    4. Systems have internal structure
    5. Systems can regulate their output by using feedback as input
    6. Systems are arbitrary
    7. Systems are purposive
