Understanding APIs
APIs, or Application Programming Interfaces, are sets of rules and protocols used to build and interact with software applications. APIs act as an intermediary layer that allows different software systems to communicate and work together, facilitating data exchange and functionality sharing without requiring them to share their entire codebase. For instance, a weather application on your phone uses an API to fetch weather data from a remote server. This allows the app to remain lightweight and focused on user interface design while leveraging complex data processing done on the server. Powered by ChatGPT-4o。
