Answer 9

Limited software, often offered with restricted features or a trial period.

Question 10

What are the benefits of free software?

Answer 10

Software that can be copied, modified, or distributed freely.

Question 11

What is open source software?

Answer 11

Software that shares intellectual property openly, allowing modifications.

Question 12

Answer 13

Software created to generate profit.

Question 14

What are the phases of SDLC?

Answer 14

Analysis, design, development, deployment, testing, and maintenance.

Question 15

What is SDLC?

Answer 15

Software Development Life Cycle

Question 16

What happens during the analysis phase?

Answer 16

Customer and end-user needs and expectations are defined and documented.

Question 17

What is the focus of the design phase?

Answer 17

Defining the software structure, including architectural and detailed design documents.

Question 18

What occurs during the development phase?

Answer 18

Coding and testing of the software.

Question 19

What are two methodologies used in the development phase?

Answer 19

Waterfall (sequential development) and agile (iterative cycles).

Question 20

What is deployment in SDLC?

Answer 20

Moving the software to the production environment, making it accessible to end-users.

Question 21

What is the purpose of testing?

Answer 21

To confirm that the software meets established specifications.

Question 22

What is maintenance in SDLC?

Answer 22

Activities to ensure the software’s proper functioning during its lifecycle.

Question 23

What is the waterfall methodology?

Answer 23

a traditional, linear approach to software development that breaks down the process into distinct, sequential phases. Each phase must be completed before the next one begins, making it a structured and systematic method. This model is particularly useful for projects with well-defined requirements and minimal expected changes.

Question 24

What is the FDD methodology?

Answer 24

(Feature-driven development) is an agile framework that organizes software development around making progress on features. FDD is customer-centric, incremental, and iterative to deliver tangible software results often and efficiently.

Question 25

What is the incremental methodology?

Answer 25

method of software development where the product is designed, implemented, and tested incrementally (a little more is added each time) until the product is finished. It involves both development and maintenance.

Question 26

What is the RAD methodology?

Answer 26

(Rapid Application Development) is an adaptive software development model based on prototyping and quick feedback with less emphasis on specific planning. In general, the RAD approach prioritizes development and building a prototype rather than planning.

Question 27

What is XP methodology?

Answer 27

Extreme Programming is a type of Agile development of Software based in Iteration methology

Question 28

What is the scrum methodology?

Answer 28

Divides the project into 2-4 week sprints, producing a software increment per sprint.

Question 29

What is the kanban methodology?

Answer 29

Uses a visual workflow management system, divided into sprints.

Question 30

What is the lean methodology?

Answer 30

Focuses on optimizing resources, divided into sprints.

Question 31

What is a software development framework?

Answer 31

A structure designed to streamline the development process.

Question 32

What is the role of an IDE in development?

Answer 32

Integrated Development Environments (IDEs) facilitate the integration of frameworks.

Question 33

How does code run on a CPU?

Answer 33

It is compiled into machine code, which consists of 0s and 1s.

Question 34

What is assembly language?

Answer 34

A low-level programming language that is closer to machine code than high-level languages.

Question 35

What is the difference between a compiler and an interpreter?

Answer 35

A compiler transforms code into an executable file, while an interpreter executes code line by line as it is transformed.
