What does API stand for in software development?

API stands for Application Programming Interface. In software development, an API serves as a set of rules and protocols that allows different software applications to communicate with one another. It defines the methods and data formats that applications can use to request and exchange information, essentially acting as a bridge between different systems, services, or components.

Understanding APIs is crucial in the context of digital advertising and tech integration, as they enable the connectivity required for data sharing, functionality extension, and the automation of tasks across various platforms. By leveraging APIs, developers can enhance the capabilities of their applications and create more dynamic, scalable, and efficient systems.

The other options listed do not accurately describe what an API is, and therefore are not relevant in the context of software development terminology.
