Interfaces

An interface is a point of interaction that allows different systems or components to communicate and work together effectively. Think of it as a contract that defines how they exchange information or commands, ensuring compatibility and smooth operation. For example, a smartphone’s touchscreen interface lets users interact with the device, while software APIs serve as interfaces for different programs to connect and share data. In essence, interfaces make it possible for diverse parts—whether hardware or software—to understand each other and function seamlessly.
