Introduction to software engineering

What is a software?

• The physical parts of a computer

• A computer program required to direct and use of computer

• A memory bank that is stored in a computer

• Electrical current that runs through the computer board

Microsoft Windows is

• a utilities software

• an operating system

• a device driver

Software does wear out and doesn't deteriorate

• True

• False

Answer explanation

Software does not wear out but it does deteriorate over time.

Software engineering involves

• Using engineering techniques and discipline in software development

• all aspect of software development through maintenance

• None of these

• All of these

Which of the following is the attributes of a good software.

• Acceptability

• Fragility

• Rigidity

• Viscocity

Answer explanation

Fragility, Rigidity & Viscosity is the characteristics of a poor software

Robert C. Martin

"Software should be written in such a way that it can

evolve to meet the changing needs of customers."

What attributes of a good software is this?

• Dependability and

  security

• Acceptability

• Maintainablity

• Efficiency

Answer explanation

Maintainability a critical attribute because software change is an inevitable requirement of a changing business environment.

Make Quality No 1 is a software principle mention by

• Davis’s Early Principles of Software Engineering

• Royce’s More Modern Principles

• Wasserman’s Fundamental Software Engineering Concepts

• Archimedes Principle

It is usually costly, 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.

• True

• False

Answer explanation

The use of software engineering principles in software development is cheaper in the long run.

Royce More Modern Approach emphasizes on

• Component-based development.

• Get it right before you make it faster

• Taking responsibility.

• Life cycle & Process

Answer explanation

Get it right before you make it faster & taking responsibilty is Davis Early Principles.(1994)

Lifecycle & Process is Wasserman’s Fundamental Software Engineering Concepts(1996)

Engineers should not misrepresent their level of competence. They should not

knowingly accept work which is out with their competence.
