MCA1040- SYSTEM ANALYSIS AND DESIGN
1. Differentiate between
real time systems and distributed systems..
Real time systems
Systems that
must produce the
output within specified
limits of time
after obtaining the requisite input are referred to as real time
systems. Real time systems include all
those systems that
have a very
small response time. Typically, a real time system consists
of the components organised in the following manner, as shown in figure below:
The
turn-around time of a real time system is very rigid. Example: Aircraft
autopilot system is a good example of a real time system. The autopilot
must respond to
an emergency
2 Differentiate between
operational information and strategic
information.
Operational information
Operational
Information is required for daily operations of the organisation such as
daily sales, billing.
With this information,
we make sure
that particular operational tasks
are fulfilled as
planned. On operational
level, you need information for day-to-day things-to-do. The information
is used to keep the daily systems running as efficiently and
3. Explain the terms:
System Attributes, Properties
and Characteristics. List the Elements of a System.
Attributes
The term ‘Attributes’
stands for functional
or physical traits
of a system. System attributes are considered as
the supposed qualities of the system. Some
examples of attributes
are temperature, location,
state, gender, income levels, etc.
·
Functional attributes
are performance parameters,
which can be measured such as reliability, safety and
maintainability.

4. What is
structured design? Illustrate
the process of modularisation. Also discuss modular
design technique.
Structured design
methodology is one of the
earliest types of
system development
methodologies. Structured Design
methodologies came into existence in
the 1980s, substituting
the earlier unplanned
and unmanageable procedures. A step-by-step

5. Define conversion.
Illustrate the various methods used for conversion
Conversion methods
The process
of converting the old system to the new system is known as conversion. This
process must be
planned and performed
in a proper manner. There
are four methods
which are common
in use. They
are explained in the following sections.
Generally, systems
conversion should be
achieved in minimum
time as possible. If
the conversion process
takes longer time,
then it creates difficulties for all persons

6. What is the
role of project
manager? List out
the various tasks performed by
the project manager.
The project manager ensures
that the project is finished timely and within the specified budget. He or she
also ensures that the system provides all advantages that were planned by the
project sponsor.
The function
of the project
manager comprises of
handling the team members, generating the project plan,
allocating resources, and being the main contact point when
