DEFINITION

Classification: 710/1

INPUT/OUTPUT DATA PROCESSING:

(under the class definition) Subject matter comprising means or steps for transferring data from one or more peripherals to one or more computers or digital data processing systems for the latter to process, store, or further transfer or for transferring data from the computers or digital data processing systems to the peripherals.

(1) Note. Classification herein requires more than nominal recitation of "peripheral device," "peripheral," "input/output," "I/O," etc.

(2)

Note. Processes and apparatus for code conversion in transferring codes from a keyboard peripheral to a computer or digital data processing system are classified elsewhere.

Code conversion for control of image data for display-including the transferring of data to be displayed via an input peripheral (e.g., keyboard, joystick, mouse, touch tablet, etc.) to a computer or digital data processing system and subsequently transferring image data to a display peripheral via a display memory or display controller are classified elsewhere. Processes and apparatus for code in transmitting data from a facsimile peripheral to a computer (e.g., by a modem) for transmission over a telephone line to another computer (e.g., by a modem) for transmission to another facsimile peripheral are classified elsewhere. See the SEE OR SEARCH CLASS notes below.

(3) Note. Processes and apparatus for detecting or correcting errors in generic electrical pulse or pulse coded data transferred from or to peripherals and for detecting and recovering from faults of peripherals, particularly transmission facility testing, memory testing, memory access block coding, bus and I/O channel fault recovery, peripheral fault recovery, and bus or I/O channel error detection or notification are classified elsewhere. See the SEE OR SEARCH CLASS notes below.

(4) Note. Processes and apparatus for transferring data to output peripherals for presenting the data on a fixed medium (i.e., a hard copy) are classified elsewhere. See the SEE OR SEARCH CLASS notes below.

(5) Note. Processes and apparatus for transferring data between a plurality of computers even if the transferring employs peripherals (e.g., modems, line adapters) are classified elsewhere. See the SEE OR SEARCH CLASS notes below. (6) Note. Processes and apparatus for accessing or controlling memories that are peripherals are classified elsewhere. See the SEE OR SEARCH CLASS notes below.

(7) Note. Processes and apparatus for furthering the security of peripherals are classified elsewhere. See the SEE OR SEARCH CLASSnotes below.
