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.
They can be differentiated in that structured
decisions have a well defined methodology for finding a 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.An example 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 been defined as 'some tangible or intangible entity which
serves to reduce uncertainty about future state or events' (Lucas, 1978). A
management information system (MIS) is 'an integrated user-machine system for
providing information to support operations, management and decision making
functions in an organization. The system utilizes computers, manual procedures,
models for analysis, planning, control and decision making, and a database'
(Davis and Olson, 1984). MIS facilitates managerial functioning. Management
information
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 which the connections are made is called the topology of the
computer network. Now I am discussing about network topology, Network topology
specifically refers to the physical layout of 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. Accessible when the program created the data
ceases 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”.
Answer:Almost a century ago, a large number of inventions took place during the
first industrial revolution. Within a short span of time, many countries became
industrialized. Now we are in the beginning of another industrial revolution.
The major cause of the second industrial revolution is the invention of
computers. Computer is the most versatile machine humans have 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.
Uses of Computer in Science and field: Scientists use computers to develop theories,
collect, analyze and test the data, and exchange of information
