Interface (software)

An interface in software is a point of interaction between two systems, such as a user and a program, or between different software applications. It defines how these systems communicate and share information. For users, interfaces are often visual, like menus and buttons in apps or websites, allowing them to input commands and receive feedback. For software systems, interfaces can be more technical, specifying how functions and data can be used or exchanged. Essentially, interfaces make it easier for people and programs to work together efficiently.
