<P> The term automatic data processing was applied to operations performed by means of unit record equipment, such as Herman Hollerith's application of punched card equipment for the 1890 United States Census . "Using Hollerith's punchcard equipment, the Census Office was able to complete tabulating most of the 1890 census data in 2 to 3 years, compared with 7 to 8 years for the 1880 census...It is also estimated that using Herman Hollerith's system saved some $5 million in processing costs" (in 1890 dollars) even with twice as many questions as during 1880 . </P> <P> Computerized data processing, or Electronic data processing represents a later development, with a computer used instead of several independent pieces of equipment . The Census Bureau first made limited use of electronic computers for the 1950 United States Census, using a UNIVAC I system, delivered in 1952 . </P> <P> The term data processing has mostly been subsumed by the newer and somewhat more general term information technology (IT). The term "data processing" is presently considered sometimes to have a negative connotation, suggesting use of older technologies . As an example, in 1996 the Data Processing Management Association (DPMA) changed its name to the Association of Information Technology Professionals . Nevertheless, the terms are approximately synonymous . </P> <P> Commercial data processing involves a large volume of input data, relatively few computational operations, and a large volume of output . For example, an insurance company needs to keep records on tens or hundreds of thousands of policies, print and mail bills, and receive and post payments . </P>
