Computer Data Processing (Paperback)

High Quality Content by WIKIPEDIA articles! Computer data processing is any process that uses a computer program to enter data and summarise, analyse or otherwise convert data into usable information. The process may be automated and run on a computer. It involves recording, analysing, sorting, summarising, calculating, disseminating and storing data. Because data is most useful when well- presented and actually informative, data-processing systems are often referred to as information systems. Nevertheless, the terms are roughly synonymous, performing similar conversions; data- processing systems typically manipulate raw data into information, and likewise information systems typically take raw data as input to produce information as output.
