Study Notes

API Overview

API stands for Application Programming Interface.

API Purpose and Specification

The purpose of an API specification is to outline the rules and protocols for building software applications that interact with a particular system or service.
An API specification defines how software components should interact with each other.

Implementing an API

When a computer system implements an API, it means that the system provides a set of predefined functions or protocols that allow other systems or applications to interact with it in a standardized way.

API vs User Interface

The main difference between an API and a user interface is that an API is used for machine-to-machine interaction, whereas a user interface is used for human-to-machine interaction.
An API is typically used for programmatic access, while a user interface is used for human interaction.
