Interface

An interface can be any of the following:

1. When referring to software, an interface is a program that allows a user to interact computers in person or over a network. An interface may also refer to controls used in a program that allow the user to interact with the program. One of the best examples of an interface is a GUI (Graphical User Interface). This type of interface is what you are using now to navigate your computer and how you got to this page.

2. Interfaces are physical devices, ports, or connections that are associated with hardware devices, such as computers. SATA and IDE are disk drive interfaces for computer hard drives, and ATAPI is an early CD-ROM interface.
