What is the full form of API?

The full form of API is Application Programming Interface.

What is an API?

An API is a set of rules and protocols that allows different software applications to communicate with each other. APIs define methods and data formats that applications can use to request and exchange information. This enables software systems to interact, share data, and extend functionalities without needing to understand the inner workings of each system.

Key Components of an API

1. Endpoints: The specific URLs where data or functions can be accessed.
2. Methods: The operations allowed, such as GET (retrieve data), POST (send data), PUT (update data), and DELETE (remove data).
3. Request/Response: The way data is sent and received, usually in JSON or XML format.

Common Uses of APIs

• Web APIs: Used for accessing web services, such as retrieving data from social media or payment gateways.
• Operating System APIs: Allow software to interact with system hardware, like file handling and networking.
• Library APIs: Provide ready-made functions in programming languages to perform specific tasks.

APIs are fundamental to modern software development, enabling applications to be modular, interoperable, and easily scalable.
