Understanding Computer Software

What are the main phases of the Software Development Life Cycle?

• Concept, Development, Evaluation, Support

• Planning, Design, Implementation, Review

• Analysis, Design, Testing, Release

• Planning, Requirements Analysis, Design, Implementation, Testing, Deployment, Maintenance

Name three types of software applications.

• Graphic Design Software

• Word Processing Software, Spreadsheet Software, Web Browsers

• Operating System Software

• Database Management Software

What is the purpose of software testing?

• To increase the software's price

• The purpose of software testing is to identify defects and ensure the quality of the software.

• To make the software more complex

• To reduce the software's functionality

Define open source software.

• Software that cannot be modified or shared

• Software that is only available for purchase

• Open source software is software with publicly accessible source code that can be modified and shared.

• Proprietary software with restricted access

What is proprietary software?

• Proprietary software is owned and controlled by a company or individual, with restrictions on use and distribution.

• Software that can be modified by anyone

• Open-source software with no restrictions

• Software that is free to use and distribute

List two advantages of open source software.

• Limited support and documentation.

• Higher costs for licensing and maintenance.

• Reduced collaboration and community input.

• 1. Greater flexibility and customization. 2. Enhanced security and innovation through community collaboration.

What are the common methods of software testing?

• Debugging

• Unit testing, integration testing, system testing, acceptance testing, regression testing, performance testing

• Documentation review

• Code review

Explain the difference between unit testing and integration testing.

• Unit testing focuses on system performance; integration testing checks for security vulnerabilities.

• Unit testing is done after integration testing; integration testing is done before unit testing.

• Unit testing tests individual components; integration testing tests interactions between components.

• Unit testing requires a complete system; integration testing requires only a single component.

What is the role of a user interface in software applications?

• To manage server-side processes.

• To store user data securely.

• To optimize database performance.

• The role of a user interface in software applications is to facilitate user interaction and enhance user experience.

What are the key principles of user interface design?

• Consistency, feedback, simplicity, accessibility, user control

• Complexity, ambiguity, user isolation, limited feedback

• Visual clutter, rigid design, user confusion, minimal interaction

• Inflexibility, excessive options, poor navigation, lack of responsiveness
