API stands for Application Programming Interface, which refers to the tools and protocols that allow software applications to communicate with each other.
APIs enable interoperability and seamless sharing of data and functionality between applications, making them crucial in the digital age.
There are different types of APIs, including web APIs for internet-based communication, library APIs for predefined functions, and operating system APIs for system resource interaction.
APIs function through requests and responses, where one application sends a request and the other provides the necessary data or action.
