SHORT QA

 

In this tutorial, You can learn important short question and answer for exams.

WHAT IS SOFTWARE PROTOTYPING ?

=> Software prototyping is the activity of creating prototypes of software applications i.e. incomplete version of the software program being developed. It is basically the demo version of any software development. It refers to building software application prototypes which displays the functionality of the product under development.

 

WRITE THE DIFFERENCE BETWEEN MODULAR COHESION AND COUPLING ? 

=>

COHESION COUPLING 
Cohesion is the indication of the relationship within module.Coupling is the indication of the relationship between modules.
Cohesion is the functional strength.Coupling is the independence among the modules.
High cohesion is the actual solution.Low coupling is the actual solution.
Cohesion is intra module concept.Coupling is the inter module concept

 

WRITE THE DIFFERENCE BETWEEN VALIDATION AND VERIFICATION OF SOFTWARE?

=>

VALIDATION VERIFICATION
It is a dynamic mechanism. It is a static mechanism.
It always involve executing the code. It does not involve executing the code.
It is computer based execution of program. It is human based checking of documents and files.

 

WHAT DO YOU MEAN BY BOTTOM-UP APPROACH IN SOFTWARE DESIGN?

=>

In bottom-up approach design the goals for a product are outlined and the assembly of a product is done on a system by system basis.

 

WHAT IS AN OBJECT ?

=>

Runtime entity is known as object. In software engineering object is a particular instance of a class where object can be a combination of variables, functions and data structures. 


WHAT ARE THE ADVANTAGES OF OBJECT ORIENTED DESIGN(OOD) OVER FUNCTION ORIENTED DESIGN (FOD) ?

=>

The advantages are 

i) Code reuse and recycling 

ii) Encapsulation

iii) Design benefits

iv) Software maintainance


DIFFERENCE BETWEEN FLOWCHART AND DFD.

=>


FLOWCHARTDFD
In a Flowchart, The arrows represent transfer of control between elements.In a DFD, The arrows represent transfer of data between elements.
Flowchart process can operate at a time. DFD process can operate in parallel.
Flowchart are the part of the single program.DFD are the part of how to flow data between model to model.

 PRESENTATION   UML- Activity and State Chart Diagram References  https://www.slideshare.net/Baskarkncet/08-state-diagram-and-activity-diagram  https://www.onlineinterviewquestions.com/uml-interview-questions/#question1    UML   UML , short for Unified Modeling Language, is a standardized modeling language consisting of an integrated set of diagrams, developed to help system and software developers for specifying, visualizing, constructing, and documenting the artifacts of software systems, as well as for business modeling and other non-software systems.  The UML is a very important part of developing object oriented software and the software development process. The UML uses mostly graphical notations to express the design of software projects.   Here's a quick look at each one of these 13 diagrams in as shown in the UML 2 Diagram Structure below:   Structure diagrams show the static structure of the system and its parts on different abstraction and implementation levels
