An adapter or adaptor is a device that converts attributes of one device or system to those of an otherwise incompatible device or system. Some modify power or signal attributes, while others merely adapt the physical form of one component to another. Universal Serial Bus USB is an industry standard that establishes specifications for cables and connectors and protocols for connection, communication and power supply between computers and equipment or peripheral devices. In commercial foodservice equipment, a USB port may allow for service diagnostics or automated programming updates e.g. with the introduction of new menu items with distinct cook times and temperatures.
