DATA PROCESSING [ˏprəʋ`sesɪɧ]
1. Read. Write down and translate the marked words.
Data processing is "the collection and manipulation of items of data to produce meaningful information.
A data processing system is "a system that accepts data as input and processes it into information as output." The process may be automated and run on a computer. It involves recording, analysing, sorting, summarising, calculating, disseminating and storing data.
Because data are most useful when well-presented and actually informative, data-processing systems are often referred to as information systems.
Data processing may or may not be distinguished from data conversion, when the process is merely to convert data to another format, and does not involve any data manipulation.
