Download PDF 1 What are the important categories of software? A computer program is a piece of programming code. It performs a well-defined task. On the other hand, the software includes programming code, documentation and user guide. It is a process of software development which is done to improve the maintainability of a software system.

Define Software Engineering The establishment and use of sound engineering principles in order to obtain economically software that is reliable and works efficiently on real machines. Differentiate Software engineering methods, tools and procedures. Tools: Automated or semi automated support for methods. Procedures : Holds the methods and tools together. It enables the timely development of computer software. Iteration always occurs and creates problem.
So the customer must have patience. What do you mean by task set in spiral Model? Each of the regions in the spiral model is populated by a set of work tasks called a task set that are adopted to the characteristics of the project to be undertaken.
What is the main objective of Win-Win Spiral Model? The customer and the developer enter into the process of negotiation where the customer may be asked to balance functionality ,performance and other product against cost and time to market.
Which of the software engineering paradigms would be most effective? Reasons: i It combines linear sequential model with iterative nature of prototyping ii Focuses on delivery of product at each increment iii Can be planned to manage technical risks 1.
Who is called as the Stakeholder? Stakeholder is anyone in the organization who has a direct business interest in the system or product to be built. Write the objective of project planning? It is to provide a framework that enables the manager to make reasonable estimates of resources, cost and schedule.
What is Boot Strapping? Write a short note on 4GT. Each tool enables the software developer to specify some characteristics of software at a higher level. What is FP? How it is used for project estimation? Function Point. It is used as the estimation variable to size the each element of the software.
It requires considerably less detailed. Estimated indirectly by estimating te number of inputs, outputs, data files, external interfaces. What is LOC? LOC : Lines of Code.
It is used as estimation variable to size each element of the software. It requires considerable level of detail.. Write the formula to calculate the effort in persons-months used in Dynamic multi variable Model? What are the two project scheduling methods? What is called support risk? What is RMMM? Risk Mitigation, Monitoring and Management Plan. It is also called Risk Aversion. What are four impacts of the project risk?
Catastrophic, Critical, Marginal, Negligible. List the tools or methods available for rapid prototyping. Rapid prototyping Speed i ii iii 4GT Reusable software components Formal specification and prototyping environments.
Write about Democratic Teams in software development. Egoless Team It is egoless team. All team members participate in all decisions. Group leadership rotates from member to member based on tasks to be performed. What is Software Architecture? The overall structure of the software and the ways in which that software provides conceptual. What are the models are used for Architectural design? Structural models Framework models Dynamic models Process models Functional models 2.
What is the need for modularity? Can achieve reusability. Best effort and complexity reduces. What are the five criteria that are used in modularity? What is cohesion? Binding 2. What is Coupling? Measure of interconnection among modules in a software structure. List the coupling factors.
Interface complexity between modules Reference to the module Data pass across the interface. Define Stampcoupling. When a portion of the data structure is passed via the module interface , then it called stamp coupling. Define common coupling. When a number of modules reference a global data area, then the coupling is called common coupling. Define temporal cohesion.
When a module contains tasks that are related by the fact that all must be executed with the same span of time, then it termed as temporal cohesion. What do you mean by common coupling? Common coupling : When a number of modules reference a global data area , then the coupling is called common coupling. Write about Real Time Systems.
It provides specified amount of computation with in fixed time intervals. RTS sense and control external devices, respond to external events and share processing time between tasks.
Define Distributed system. It consists of a collection of nearly autonomous processors that communicate to achieve a coherent computing system. What do you mean by factoring? It is also called vertical partitioning. It follows Top-Down strategy. We can say that there are some top level modules and low level modules.
Top level modules Control functions ,actual processing work Low level modules Workers. Performing all input computation and output tasks. What is called object points? It is an indirect software measure that is computed using counts of te number of screens, reports and components. Compare Data Flow Oriented Design with data structure oriented design Data flow oriented design : Used to represent a system or software at any level of abstraction.
Data Structure oriented design : It is used for representing information hierarchy using the three constructs for sequence, selection and repetition. Define Architectural Design and Data Design. Architectural Design : To develop a modular program structure and represent the relationships between modules.
Data Design : To select the logical representations of data objects , data storage and the concepts of information hiding and data abstraction.
Write a short note on structure charts. These are used in architectural design to document hierarchical structure, parameters and interconnections in a system. No Decision box. Mention the different types of software matrices. Productivity Metrics.
Quality Metrics. Technical Metrics. Size-Oriented Metrics. Function oriented Metrics. Human-oriented Metrics. What is Direct Measure? Direct measures in software focus on attributes that can be measured directly by examining the process product on the resources applied. What is Indirect Measure? Indirect measures are determined by establishment on empherical relationship between the measure desired and other attributes of the entity.
What is Software Quality Assurance?
