GENERAL STATEMENT OF THE CLASS SUBJECT MATTER
This class provides for an electrical computer or digital dataprocessing system or corresponding data processing method includingapparatus or steps for exchanging data or messages between two executingprograms or processes, independent of the hardware usedin the communication.
(1)Note. Classification herein requires more than nominalrecitation of the data or message exchange between two executingprograms or processes.
(2)Note. If the programs or processes are drawn to specificprocessing environments such as database/file processing, business processing, ornetworking, these programs or processes are classifiedelsewhere.
SCOPE OF THE CLASS
This class is limited to digital data processing systems andfunctions for communication between programs or processes.
Hardware mechanisms such as bus transaction processing anddata transfer between computers and digital data processing systemsare classified elsewhere. See the SEE OR SEARCH CLASS notesbelow.
LINES WITH OTHER CLASSES
A. Electrical Computers and Data Processing Systems, RelatedSystems and Functions in General
This class is for communication between programs or processes.Communication between computers or digital data processing systemsand peripherals is classified elsewhere. See the SEE ORSEARCH CLASS notes below.
B. Communication Classes
The basic distinctions between this class and the communicationsclasses are:
(A) The subclasses here include a digitaldata processing system or computer, rather than other datacommunications devices, and
(B) The communication herein is betweenprograms or processes in a digital data processing system or computer. Seethe SEE OR SEARCH CLASS notes below.
Overall combinations directed to a system for performing communicationsfunctions only is classified in the appropriate communication class. Seethe SEE OR SEARCH CLASS notes below for examples.
Preprocessing or postprocessing of signals in a data transferto effect a particular communications method (e.g., modulating, demodulating, encoding, decoding, or phaselocking) is classified in the appropriate communicationsclass. See the SEE OR SEARCH CLASS notes below for examples.
C. Other Classes
Subject matter relating to transmission or interconnectionsystems not classifiable herein and not appropriate for the communicationclasses should be classified in the residual class for all transmissionor interconnection systems. See the SEE OR SEARCH CLASSnotes below.
