    en.wikipedia.org/wiki/Inforex_1300_Systems

    Inforex Inc. corporation manufactured and sold key-to-disk data entry systems in the 1970s and mid-1980s. The company was founded by ex-IBM engineers to develop direct data entry systems that allowed information to be entered on terminals and stored directly on disk drives, replacing keypunch machines using punched cards or paper tape, which had been the dominant tools for data entry since the ...

  3. Boolean model of information retrieval - Wikipedia

    en.wikipedia.org/wiki/Boolean_model_of...

    The (standard) Boolean model of information retrieval (BIR) [1] is a classical information retrieval (IR) model and, at the same time, the first and most-adopted one. [2] The BIR is based on Boolean logic and classical set theory in that both the documents to be searched and the user's query are conceived as sets of terms (a bag-of-words model ).

  4. Evaluation measures (information retrieval) - Wikipedia

    en.wikipedia.org/wiki/Evaluation_measures...

    Evaluation measures for an information retrieval (IR) system assess how well an index, search engine, or database returns results from a collection of resources that satisfy a user's query. They are therefore fundamental to the success of information systems and digital platforms.

    IBM 3740 Data Entry System was a data entry system that was announced by IBM in 1973. It recorded data on an 8" diskette, a new recording medium from IBM, for fast, flexible, efficient data entry to either high-production, centralized operations or to decentralized, remote operations. [ 1 ]

  6. Two-pass verification - Wikipedia

    en.wikipedia.org/wiki/Two-pass_verification

    Two-pass verification, also called double data entry, is a data entry quality control method that was originally employed when data records were entered onto sequential 80-column Hollerith cards with a keypunch. In the first pass through a set of records, the data keystrokes were entered onto each card as the data entry operator typed them.

  7. IBM System/3 - Wikipedia

    en.wikipedia.org/wiki/IBM_System/3

    The System/34 and System/36 both had two processors: a Control Storage Processor (CSP), as in System/32, which handled most supervisor and input/output operations, and a Main Storage Processor (MSP). This latter was a re-implementation of the System/3 model 15 processor; effectively providing "hardware emulation" of the System/3.

    Global Command and Control System (GCCS) is the United States' armed forces DoD joint command and control (C2) system used to provide accurate, complete, and timely information for the operational chain of command for U.S. armed forces. "GCCS" is most often used to refer to the computer system, but actually consists of hardware, software ...

  9. Data entry - Wikipedia

    en.wikipedia.org/wiki/Data_entry

    Data entry is the process of digitizing data by entering it into a computer system for organization and management purposes. It is a person-based process [ 1 ] and is "one of the important basic" [ 2 ] tasks needed when no machine-readable version of the information is readily available for planned computer-based analysis or processing.
