Abstract: An entry for a file to be stored in a file system can be created. A priority is assigned to the file that indicates an importance of the file relative to a plurality of additional files stored in the file system, the priority being one of three or more priorities available to files in the file system. Additionally, one or more of the files that are associated with the lowest priority values can be automatically deleted.

Abstract: A first installation package for a first group of files is created for a program. The first group of files include language-neutral files for the program but no language-specific files for the program. A second installation package for a second group of files is also created for the program. The second group of files includes language-specific files for the program.

Abstract: A portable storage device includes an interface and one or more flash memories. The one or more flash memories store one or more executable files that can be executed by a host computer to which the device is coupled without altering any environment settings on the host computer even though the one or more executable files include instructions to access environment settings. Additionally, the application is bound to the portable storage device during an activation process.

Abstract: A three level network microprocessor based nodal architecture for a fiber optic local area network communication system is disclosed in which the processing responsibility for establishing a voice, video or data communication link between an initiating I/O device and a recipient I/O device and for subsequent two way data exchange between the initiating and recipient devices are shared between three levels of digital processing capability in such manner as to demand the least amount of time from the highest, most intelligent processing level common to all devices thereby making more efficient use of its processing capability as an overall supervisory processor. Each I/O device whether it be a digital terminal, computer or telephone set interfaces with a nodal system through a middle level of processor.
