What is the full form of api?

API stands for Application Programming Interface.Short, friendly explanation: An API is a set of rules and tools that lets one piece of software talk to another. Imagine an API as a waiter — you (the app) place an order (request) and the waiter (API) brings back your food (response) from the kitchen (server).Why it matters: - Developers use APIs to connect apps, get data, or control services (for example, a weather API returns current weather to a mobile app). - Types: Web APIs (HTTP/REST), library APIs (functions you call inside code), hardware APIs (device drivers).
