Ethical dilemmas Give me

Heterogeneity

Increasingly, systems are required to operate as distributed systems across networks that include different types of computer and mobile devices.

Intellectual property rights Computer misuse Confidentiality Competence

Issues of professional responsibility give all

False: It is usually cheaper, in the long run, to use software engineering methods and techniques for software systems rather than just write the programs as if it was a personal programming project

It is usually more expensive, in the long run, to use software engineering methods and techniques for software systems rather than just write the programs as if it was a personal programming project. (T or F)

False: Some fundamental principles apply to all types of software system, irrespective of the development techniques used:

No fundamental principles apply to all types of software system, irrespective of the development techniques used: (T or F)

False: Software engineers have responsibilities to the engineering profession and society. They should not simply be concerned with technical issues.

Software engineers should simply be concerned with technical issues. (T or F)

True

User interfaces are constrained by the capabilities of web browsers. ( T or F)

Dependability and security

Software dependability includes a range of characteristics including reliability, security and safety. Dependable software should not cause physical or economic damage in the event of system failure. Malicious users should not be able to access or damage the system.

True

Software engineering is concerned with theories, methods and tools for professional software development. (T or F)

MANAGEMENT

Software engineering managers and leaders shall subscribe to and promote an ethical approach to the management of software development and maintenance.

PUBLIC

Software engineers shall act consistently with the public interest

PROFESSION

Software engineers shall advance the integrity and reputation of the profession consistent with the public interest.

COLLEAGUES

Software engineers shall be fair to and supportive of their colleagues.

PRODUCT

Software engineers shall ensure that their products and related modifications meet the highest professional standards possible.

JUDGMENT

Software engineers shall maintain integrity and independence in their professional judgment.

SELF

Software engineers shall participate in lifelong learning regarding the practice of their profession and shall promote an ethical approach to the practice of the profession.

Computer misuse

Software engineers should not use their technical skills to misuse other people's computers

Truthy

Software reuse is the dominant approach for constructing web-based systems(T or F)

Maintainability

Software should be written in such a way so that it can evolve to meet the changing needs of customers. This is a critical attribute because software change is an inevitable requirement of a changing business environment.

Efficiency

Software should not make wasteful use of system resources such as memory and processor cycles.

Customized products

Software that is commissioned by a specific customer to meet their own needs.

Generic products

Stand-alone systems that are marketed and sold to any customer who wishes to buy them.

Customized products

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

Generic products

The specification of what the software should do is owned by the software developer and decisions on software change are made by the developer

False: There are many different types of software system and there is no universal set of software techniques that is applicable to all of these

There are many different types of software system and there is a universal set of software techniques that is applicable to all of these. (T or F)

Stand-alone applications

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.

Batch processing systems

These are business systems that are designed to process data in large batches. They process large numbers of individual inputs to create corresponding outputs.

Embedded control systems

These are software control systems that control and manage hardware devices. Numerically, there are probably more embedded systems than any other type of system.

Systems of systems

These are systems that are composed of a number of other software systems.

Systems for modeling and simulation

These are systems that are developed by scientists and engineers to model physical processes or situations, which include many, separate, interacting objects

Acceptability

This means that it must be understandable, usable and compatible with other systems that they use.

True

To ensure, as much as possible, that their efforts will be used for good, software engineers must commit themselves to making software engineering a beneficial and respected profession. (T or F)

Computer science focuses on theory and fundamentals; software engineering is concerned with the practicalities of developing and delivering useful software.

What is the difference between software engineering and computer science?

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.
