SOFTWARE ENGINEERING CH:1-5ACCURATE QUESTIONS AND
ANSWERSW WITH SOLUTIONS 2024
(Ch.1) Increasing system complexity - ANSWER As new software engineering techniques help us to build
larger, more complex systems, the demands change. Systems have to be built and delivered more
quickly; larger, even more complex systems are required; systems have to have new capabilities that
were previously thought to be impossible.
(Ch.1) Failure to use software engineering methods - ANSWER It is fairly easy to write computer
programs without using software engineering methods and techniques. Many companies have drifted
into software development as their products and services have evolved. They do not use software
engineering methods in their everyday work. Consequently, their software is often more expensive and
less reliable than it should be.
(Ch.1) Software costs - ANSWER often dominate computer system costs. The costs of software on a PC
are often greater than the hardware cost
Software costs more to maintain than it does to develop. For systems with a long life, maintenance costs
may be several times development costs
(Ch.1) What is software? - ANSWER Computer programs and associated documentation. Software
products may be developed for a particular customer or may be developed for a general market.
(Ch.1) What are the attributes of good software? - ANSWER Good software should deliver the required
functionality and performance to the user and should be maintainable, dependable and usable.
(Ch.1) What is software engineering - ANSWER Software engineering is an engineering discipline that is
concerned with all aspects of software production
(Ch.1) What are the fundamental software engineering activates? - ANSWER -Software Specification
-Software Development
-Software Validation
-Software Evolution
,(Ch.1) What is the difference between software engineering and computer science - ANSWER Computer
science focuses on theory and fundamentals software engineering is concerned with the practicalities of
developing and delivering useful software
(Ch.1) What is the difference between software engineering and system engineering - ANSWER System
engineering is concerned with all aspects of computer-based systems development including hardware
software and process engineering software engineering is part of this more general process
(Ch.1) What are the key challenges facing software engineering - ANSWER Coping with increasing
diversity, demands for reduced delivery times and developing trustworthy software
(Ch.1) What are the costs of software engineering - ANSWER Roughly 60% of software costs are
development cost and 40% testing costs. For custom software evolution costs often exceed development
costs
(Ch.1) What are the best software engineering techniques and methods` - ANSWER While all software
projects have to be professionally managed and developed different techniques are appropriate for
different types of systems for example games should always be developed using a series of prototypes
whereas safety critical control systems require a completes and analyzable specification to be developed
you cant therefore say that one method is better then another
(Ch.1) What differences has the web made to software engineering? - ANSWER The web has led to the
availability of software services and the possibility of developing highly distributed service-based
systems. Web-based systems development has led to important advances in programming languages and
software reuse.
(Ch.1) Software Products - ANSWER Generic products
Customized products
(Ch.1) Generic products - ANSWER -Stand-alone systems that are marketed and sold to any
customer who wishes to buy them
-Examples - PC software such as graphics programs,
project management tools; CAD software; software for
,specific markets such as appointments systems for
dentists
(Ch.1) Customized products - ANSWER -Software that is commissioned by a specific customer
to meet their own needs
-Examples - embedded control systems, air traffic
control software, traffic monitoring systems
(Ch.1) Product specification - ANSWER Generic products
Customized products
(Ch.1) Generic products - Specification - ANSWER The specification of what the software should do is
owned by the software developer and decisions on software change are made by the developer or
software product owner.
(Ch.1) Customized products - Specification - ANSWER The specification of what the software should do is
owned by the customer for the software and they make decisions on software changes that are required
(Ch.1) Essential Attributes of Good Software - ANSWER -Maintainability
-Dependability and security
-Efficiency
-Acceptability
(Ch.1) Software engineering - ANSWER an engineering discipline that is concerned with all aspects of
software production from the early stages of system specification through to maintaining the system
after it has gone into use
(Ch.1) Software process activities - ANSWER specification, development, validation, evolution
(Ch.1) Software Development Life Cycle - ANSWER
, (Ch.1) Issues that affect software - ANSWER Heterogeneity
Business and social change
Security and trust
Scale
(Ch.1) Software engineering diversity - ANSWER There are many different types of software system and
there is no universal set of software techniques that is applicable to all of these
The software engineering methods and tools used depend on the type of application being developed,
the requirements of the customer and the background of the development team
(Ch.1) Application Types - ANSWER - Stand-Alone Applications
- Interactive Transaction-based Applications
- Embedded Control Systems
- Batch Processing Systems
- Entertainment Systems
- Systems for Modeling and Simulation
- Data Collection Systems
- Systems of Systems
(Ch.1) Stand-alone applications - ANSWER These are application systems that run on a local computer,
such as a PC. They include all necessary functionality and do not need to be connected to a network.
(Ch.1) Interactive transaction-based applications - ANSWER Applications that execute on a remote
computer and are accessed by users from their own PCs or terminals. These include web applications
such as e-commerce applications.
(Ch.1) Embedded control systems - ANSWER These are software control systems that control and
manage hardware devices. Numerically, there are probably more embedded systems than any other
type of system.
(Ch.1) batch processing system - ANSWER These are business systems that are designed to process data
in large batches. They process large numbers of individual inputs to create corresponding outputs.
