What Does 'Built On' Mean in Software Development?

The term 'built on' in the context of software development refers to creating new applications, software, or features based on existing technologies, frameworks, platforms, or tools. This concept is crucial for both understanding how software is developed and the collaborative nature of the tech industry.

1. Understanding Layers of Technology

To grasp what 'built on' entails, let's break it down into layers:

• Base Layer: This includes programming languages (like Python, Java, or C#) and hardware that provide the foundational capabilities for building software.
• Frameworks: These are pre-built libraries and tools that simplify the development process, such as React for web development, Django for web applications, or TensorFlow for machine learning.
• Platforms: Some software is built to run on platforms like iOS, Android, or cloud services such as AWS. Developers create applications designed for specific operating environments.

2. Why Build On Existing Technologies?

Building on existing technologies allows developers to:

• Save Time: Instead of starting from scratch, they utilize established code, libraries, and frameworks, which speeds up the development process.
• Increase Reliability: By using tested and proven technologies, developers can reduce bugs and increase software stability.
• Focus on Innovation: They can concentrate on unique features or functionalities rather than reinventing the wheel.

3. Examples of Software Built On Other Technologies

To illustrate the concept, consider these examples:

• Web Applications: Many web applications are built on frameworks like Angular or Ruby on Rails, which offer powerful tools and components to create interactive user experiences.
• Mobile Apps: Applications for smartphones often use platforms such as Flutter or React Native, which allow developers to create apps for both Android and iOS from a single codebase.
• APIs: Developers build applications that interact with existing APIs (Application Programming Interfaces) to leverage functionalities provided by platforms like Google Maps or social media networks.

4. Conclusion

In summary, understanding that many modern software applications are built on existing technologies is key for any aspiring developer, especially at your age when you’re likely exploring programming for the first time. By leveraging existing frameworks, languages, and platforms, you’ll be better equipped to innovate and create valuable applications in the tech world.
