API (Application Programming Interface)
An API, or Application Programming Interface, is a set of defined rules and protocols that allow different software applications to communicate with each other. It enables developers to use predefined functions and services, thereby facilitating faster and more efficient software development. Rather than writing every piece of code from scratch, developers can leverage APIs to connect and interact with other software components, services, or systems. APIs can be used for a variety of purposes, such as integrating different systems, accessing third-party services, or extending the functionality of existing applications. They are essential tools in modern software development, providing support for multiple programming languages and platforms.
