What is an API?
- An Application Programming Interface (API) is a set of rules and protocols that allows different software applications to communicate with each other.
How Do I Remember It?
- Think of an API as a waiter in a restaurant. The waiter (API) takes your order (request) to the kitchen (server) and brings back your food (response). It's the messenger that lets different parts of a system communicate.
Real World Example
- When you use a weather app on your phone, it uses an API to fetch weather data from a weather service. The app sends a request to the weather service's API, and the API returns the current weather data in a format the app can understand and display.
