Pronounced "gee-nee." A Java-based distributed computing environment from Sun in which devices can be plugged into the network and automatically offer their services and make use of other services on the network. Jini creates a "network dialtone" allowing, for example, any PDA or laptop to be plugged in and immediately be able to use printers and other resources. It turns "peripherals into services," so that when a disk drive is plugged in, it becomes a storage service rather than just another disk drive. See JavaSpaces and zero configuration.
