Today’s modern amateur radio devices are equipped with RS-232 port, (or with a derivation of RS-232 port), for a control via computer. Ethernet connections are commonly used for networking, which is why most cable modems and routers have an Ethernet interface. Several common peripherals connect to a computer via USB, while other devices use a Firewire connection or other interface. The printer itself also has a USB interface, which is where the other end of the USB cableĬonnects. Therefore, the USB port on the computer is considered as the hardware interface. For example, a printer typically connects to a computer via Parallel port or via USB interface. It can also be used as a verb, describing how two devices connect to each other.Ī hardware interface is used to connect two or more electronic devices together. The term “interface” can refer to either a hardware connection or a user interface. The term is used in many fields, including chemistry, geology, electronics, computers (both hardware and software) and telecommunications. The connection can be either physical or logical. By a definition, an interface is a shared boundary or connection between two dissimilar objects, devices or systems through which information is passed.
