A system is described for maintaining synchrony of operations among a plurality of devices that have independent clocking arrangements. The system includes a task distribution device that distributes tasks to a synchrony group comprising a plurality of devices that are to perform the tasks distributed by the task distribution device in synchrony. The task distribution device distributes each task to the members of the synchrony group over a network. Each task is associated with a time stamp that indicates a time, relative to a clock maintained by the task distribution device, at which the members of the synchrony group are to execute the task. Each member of the synchrony group periodically obtains from the task distribution device an indication of the current time indicated by its clock, determines a time differential between the task distribution device's clock and its respective clock and determines therefrom a time at which, according to its respective clock, the time stamp indicates that it is to execute the task.

In a digital data processing system having an on-line file system component, a method and apparatus for archiving the contents of a selected client volume stored on the file system. The archiving is performed automatically, beginning with an initial duplication of the existing contents of the client volume into an archive volume, then continuing as changes, including additions, deletions and modifications, are made to the files comprising the client volume. Older, previously-archived versions of modified files are gracefully discarded so as to moderate the rate of growth of the archive volume. The archive volume may be used to restore the client volume, either selectively or in whole, in the event of inadvertent damage to, or loss of, files in the client volume.

From a text entry tool, a digital data processing device receives inherently ambiguous user input. Independent of any other user input, the device interprets the received user input against a vocabulary to yield candidates such as words (of which the user input forms the entire word or part such as a root, stem, syllable, affix), or phrases having the user input as one word. The device displays the candidates and applies speech recognition to spoken user input. If the recognized speech comprises one of the candidates, that candidate is selected. If the recognized speech forms an extension of a candidate, the extended candidate is selected. If the recognized speech comprises other input, various other actions are taken.
