Lesson 17: Software Development Concepts

Question 1

What are the steps in Software Development Lifecycle (SDLC)?

Answer 1

● Requirements Gathering: Like discussing the blueprint
of a building with an architect.

● Design: Creating the blueprint based on requirements.

●Implementation/Construction: Builders (developers) construct the building (write the code).

● Testing: Inspecting the building (software) for any issues.

● Deployment: Opening the building (software) for use.

● Maintenance: Regular upkeep and improvements,
similar to a building’s maintenance.

Question 2

What are the different Methodologies in software development?

Answer 2

1. Waterfall
2. Agile

Question 3

What the steps in waterfall?

Answer 3

REQUIREMENTS

DESIGN

IMPLEMENTATION

TESTING

MAINTENANCE

Question 4

What are the steps in agile?

Answer 4

1. Design
2. Test
3. Analyze
4. Define

Question 5

What are some key aspects of waterfall?

Answer 5

● A sequential software
development methodology.

● Follows a linear approach, where each phase is completed
before moving to the next.

● Suitable for projects with
well-defined and unchanging requirements.

● Not ideal for projects requiring
frequent changes or iterations.

Question 6

What are some key aspects of agile?

Answer 6

● An iterative and collaborative approach
to software development.

● Emphasizes flexibility, adaptability, and
customer satisfaction.

● Key concepts include:
- Iterative development: Breaks the project into
smaller iterations or sprints.

• Sprints: Timeboxed periods (usually 1-4 weeks) to complete a set of tasks.
• User stories: Descriptions of specific features or
  functionality from the user’s perspective.

Question 7

What does DevOps stand for?

Answer 7

(development+operations)

Question 8

In DevOps, ___________ and _________ work closely, similar to a professional restaurant kitchen. Chefs prepare dishes (developers
write code).

Answer 8

Chefs (developers) & servers (operations)

● Servers deliver dishes to customers (operations deploy code to end users).

● Servers relay customer feedback to
chefs (operations relay user feedback
to developers).

Question 9

What is the aim in DevOPs?

Answer 9

High-quality ‘food’ (software) delivered quickly and efficiently.

Question 10

What is Integrated Development Environment (IDE)

Answer 10

An Integrated Development Environment (IDE)
is like a comprehensive tool kit for programmers.

It provides all the tools needed to develop software in one convenient place!

Question 11

Why Use an IDE?

Answer 11

● Simplifies code writing
● Speeds up development
● Helps in identifying and fixing errors, making the entire process of creating software more efficient and enjoyable.

Question 12

What are the different Software Applications?

Answer 12

1. Desktop applications
2. Web applications
3. Mobile applications

Advantages
● Offline access to data and functionality.
● Greater control over the user interface and user experience.

Challenges
● Platform-dependent, requiring different versions for different operating systems.
● Installation and updates can be more complex for users.

Question 17

What are some characteristics, advantages, & challenges of Web Applications?

Answer 17

Characteristics
● Accessed and utilized through web browsers.
● Often rely on server-side processing and client-side scripting.

Advantages
● Cross-platform compatibility, accessible from any device with a browser and internet connection.
● Easier deployment and updates since changes are made on the server.

Challenges
● Reliance on internet connectivity.
● Limited access to system resources compared to desktop applications.

Question 18

What are some characteristics, advantages, & challenges of Mobile Applications?

Answer 18

Characteristics:
● Designed specifically for smartphones and tablets.
