Each chain deliberately caters to a very different market -- Starwood to those that appreciate and are willing to sort through their wonderfully different brands, hotels, and locations; Marriott to those to whom thoughtful and consistent service is more important than a trendy setting.
Interface (computing) In computing, an interface is a shared boundary across which two or more separate components of a computer system exchange information. The exchange can be between software, computer hardware, peripheral devices, humans and combinations of these. Some computer hardware devices, such as a touchscreen, can both send and receive data through the interface, while others such as a mouse or microphone may only provide an interface to send data to a given system.
Just as the API provides a consistent way for applications to use the resources of the computer system, a user interface (UI) brings structure to the interaction between a user and the computer.
