A computer is an electronic device that can accept data as input, process it mathematically or logically, and output meaningful information. Data refers to raw facts or numbers and can include things like lists of names or keywords. Information is data that has been processed into a useful and meaningful form. Data processing manipulates and transforms data through operations like gathering, interpreting, recording, and summarizing data to gain new knowledge and is done manually, through mechanical means, or electronically using computers.

What is Data?Data – are raw facts or figures. They are made up letters, numbers and other symbols or special characters.can be list of phone numberslist of students namesa set of keywords jotted during a speech
Informationrefers to data that have been processed into a form that is meaningful and useful.
Data Processing – is the manipulation and transformation of data into meaningful results.
Examples of the operations used in data processing include the following:Gathering DataInterpretation and classification of dataRecording of DataPerforming basic mathematical operationsSummarizing the results
Data processing is a routinely activity of all people. It’s what we do to gain and develop new knowledge. It is actually a cycle. As you read you will understand why.

 TYPES OF DATA PROCESSINGManual Data ProcessingManual – mechanical data processingElectronic data processing
Manual Data Processing – is characterized by the absence of any machine in processing data.The person involved does all the activities – from accumulation of data, their manipulation and the creation of results
Manual mechanical data processing- devices are used In processing but human intervention is needed to produce results.
Electronic data processing – refers to the use of computer in processing data.
