Question.1. Define structured and unstructured decisions. Discuss the rational individual models
of decision making. What are the implications of these models to information system analysts?
Answer:Decisions can vary from structured to unstructured.
Theycan be differentiatedinthatstructureddecisionshave awell definedmethodologyforfindinga
solution and have the data to reach a decisions. They are usually straight forward and made on a
regular basis.An example of a structured decision in my company is whether or not to withdraw
funds from an international account depending on the current exchange rate.
Unstructured decision rely on knowledge and/or expertise and often require data and models to
solve.Anexample of an unstructured decision in my company is what types of new content should
be created and what market should be targeted.
Question.2. How much importance should be accorded to implementation phase as part of the
total MIS development activity? Explain. Briefly discuss the various implementation strategies.
Under what circumstances are they suitable?
Answer:Information is a set of classified and interpreted data used in decision making. It has also
beendefinedas'some tangible orintangible entitywhichservesto reduce uncertainty about future
state or events' (Lucas, 1978). A management information system (MIS) is 'an integrated user-
machine systemforprovidinginformationtosupportoperations,managementand decision making
functionsinanorganization.The systemutilizescomputers,manual procedures,modelsforanalysis,
planning, control and decision making, and a database' (Davis and Olson, 1984). MIS facilitates
managerial functioning. Management information

2. Question.3. What are the various kinds of network topologies? Describe the types of switching
available in networks and describe the various applications to which networks can be put.
Answer:The way in whichthe connectionsare made iscalledthe topologyof the computernetwork.
Now I am discussing about network topology, Network topology specifically refers to the physical
layoutof the network,especially the locations of the computers and how the cable is run between
them.
Four most common topologies are:
Bus Topology:All the devices on a bus topology are connected by one single cable. When one
computer sends a signal up the wire, all the computers on
Question.4. Outline the basic sequence of steps to acquiring a DMBS. What steps are the most
important? Why should an organization be careful about placing over reliance on “benchmark”
tests in selecting a DBMS?
Answer:DBMS has to be persistent. Accessiblewhenthe programcreatedthe dataceases to exist or
even the application that created the data restarted. It has to provide some uniform methods
independent of a specific application for accessing the information that is stored.DBMS does not
impose any constraints or security with regard to data manipulation. DBMS are for smaller
organizations with small amount of data, where security not major concern.
Database is a collection of related data and data is a collection of facts and figures that can be
processed to produce information.
Mostly data represents recordable facts. Data aids in
Question.5. Write a detailed note on “the impact of computerization on our living style”.

inventionof computers.Computeristhe mostversatile machinehumanshave ever created. It plays
an important role in our everyday life. It covers huge area of application including education,
industries, government, medicine, and scientific research, law and even music and arts. Without
computers, life wound certainly be difficult and different.
