DEFINITION

Classification: 709/200

MULTICOMPUTER DATA TRANSFERRING:

(under the class definition) Subject matter further comprising means or steps for transferring data among a plurality of spatially distributed (i.e., situated at different locations) computers or digital data processing systems via one or more communications media (e.g., computer networks) wherein the computers or digital data processing systems employ the data in data processing before or after the transferring, and wherein the data processing affects the data transfer between the computers.

(1) Note. The subject matter of this subclass is characterized by data transfer occurring as an external communication between separate computers which themselves are distinguishable processing entities.

(2) Note. The basic distinctions between this subclass together with its indented subclasses and the communications classes are (a) the subclasses herein include computers, rather than other data communications devices, and (b) the computers perform data processing in addition to transferring data there between; overall combinations directed to a system for performing communications functions only are classified in the communications art classes. See the SEE OR SEARCH CLASS notes below.

(3)

Processes and apparatus for preprocessing or postprocessing of signals in the data transfer to effect a particular method of communications (e.g., modulating, demodulating, encoding,

decoding, phase locking) is classified in the appropriate communications class. See the SEE OR SEARCH CLASS notes below for examples.

(4) Note. Subject matter relating to transmission or interconnection systems not classifiable herein and not appropriate for the communication classes is classified in the residual class for all transmission or interconnection systems. See the SEE OR SEARCH CLASS notes below.

(5) Note. Processes and apparatus for error detection and correction (EDAC), fault detection and recovery, and for increasing the probability of a computer, digital data processing system, or computer network performing correctly (i.e., increasing its reliability and availability), per se, are classified elsewhere. See the SEE OR SEARCH CLASS notes below. (6) Note. Processes and apparatus for enhancing the security of computers, digital data processing systems, and computer networks, per se, are classified elsewhere. See the SEE OR SEARCH CLASS notes below.

(7) Note. Processes and apparatus for housing or mounting computers, digital data processing systems, calculators, or components thereof are classified elsewhere. See the SEE OR SEARCH CLASS notes below.

(8) Note. Subject matter relating to neural networks, per se, are classified elsewhere. See the SEE OR SEARCH CLASS notes below.

(9) Note. Subject matter relating to distributed or remote accessing of databases or files, per se, is classified elsewhere. See the SEE OR SEARCH THIS CLASS, SUBCLASS notes below.
