The Fundamentals of Application Development:

In today’s digital world, applications are at the heart of how we interact with technology. From mobile apps that keep us connected to web applications that power businesses, the demand for skilled developers is higher than ever. Whether you’re just starting out or looking to expand your development knowledge, understanding the fundamentals of application development is essential.

What is Application Development?

Application development is the process of designing, building, testing, and deploying software applications. These applications can run on various platforms, including mobile devices (iOS and Android), web browsers, and desktops.

Types of Applications

Before diving into the technical aspects, it’s important to know the different types of applications:

1. Web Applications – These are apps that run in a web browser and don’t require installation, such as Gmail, Trello, or Facebook.

2. Mobile Applications – Apps designed specifically for mobile devices, available on platforms like the App Store and Google Play.

3. Desktop Applications – Software installed directly on a computer, such as Adobe Photoshop or Microsoft Word.

4. Hybrid Applications – A combination of web and mobile apps, hybrid apps are built using web technologies but run inside a native mobile shell.

Key Stages of Application Development

1. Planning & Research

   • Define the purpose of the application

   • Identify the target audience

   • Conduct market research to understand user needs

2. Designing the UI/UX
