2. Q: What is System?
Definition: system is a group or set of components that
interact and work together to complete a specific task.

Monitor Keyboard and other devices, which together
interact with each other and process the data.
Every system depends on the information system where
data flows from one person to another or one department
to another.

4. This information system serves almost all the business
system by linking all the components of business and the
produce valuable information in the form of data.

5. Q: Give the Definition of System Analysis and System
Design.
• System Analysis: It is the process of gathering &
interpreting facts, diagnosing problems & using the
information to recommended improvements to the system.
• System Design: It is the process of planning a new
business system or one to replace or complement an
existing system.
• The system design is like the blue print for a building, it
specifies all the features to be finished.
• Analysis specifies what the system should do. Design states
how to accomplish the objective.

6. Q : Give the Definition of System analyst:
• A system analyst’s major role is to identify information
needs of an organization system. Even feasibility study,
eventual design & implementation of computer system are

• “ A person who conducts a methodical study & evaluations of
an activity such as a business to identify its desired objective
in order to determine procedures by which objectives can be
gained.” (By Random house Dictionary).

constraints and to translate these into a viable operation.”
(By John Nicholas)

design of an information system which will meet these
needs.

System Analysis only:
• The analyst’s only role is conducting system studies to
learn relevant facts about business activity. The emphasis
is on gathering information & determining requirements.

9. System Analysis & Design:
• Analysts carry out complete system study but have added
responsibility of designing the new system.
• People, who are responsible for both systems analysis &
design, work on fewer projects.
System analysis, Design & programming:
• Analysts conduct the system investigation; develop design
specification & program s/w to implement the design.

10. Q: What is Subsystem?
One system is simplified and decomposed into number of
many small systems which are known as sub system.
Output of first system becomes an input for the other.
Q: What is Business System?

meaning the supply of goods and services.
A business can span one or several business systems.

11. Q: What is Information System?
Every organization system depends on an information system.
This system shows the data flow from one person/department
to another.
Information system supports the business activities by
performing various activities like processing of input data,
maintaining the data and files, produces information, reports
and other output.
Information system consists of subsystems, including
hardware, software & data storage for files & database.
The particular set of sub-system used for specific task is known
as information system application.

12. There are mainly 3 types of Information system exists in
the world.
They are as follows:
1. Transaction Processing system (TPS)
2.Management information system (MIS)
3.Decision support system (DSS)
