Review on ELECTRONIC DATA PROCESSING(E.D.P)

The Data processing means transformation of data into more meaningful results for carrying out scientific, business activties.The result of data processing is called "INFORMATION". The transformation of data consist of a sequence of operations. The sequence is called "PROCEDURE". Input- Processing-Output: Data processing is a system which takes data as an input, carries out the required processing on the data and produces the information. The system is called "MANUAL" when processing is performed by human beings and "AUTOMATIC" when machines are used. When computers are used for data processing the system is called"ELECTRONIC DATA PROCESSING". Elements of E.D.P The 5 elements are how can work or using: #Hardware-all phisical parts which makes up a computer system called hardware i.e. all the devices or peripherals which performs the data processing operations. #Software- consists of programs and routines whose purpose is to make the computer useable for the user.The software normally supplied by computer manufacturers or software manufacturers. #User program -a program consist of related instructions to perform operations. A data processing job may require a number of programs. #Procedure-the operation of data processing system requires procedure for use, in preparing data, for operating the computer and distributing the output after processing. #Personnels-E.D.P. basically needs tree kinds of skilled personnels. a.System Analyst b.Programmer c.Operator A)System analyst-studies information needs and data processing requirements,design a data processing system and prepare specification. B)Programmer-writes a programmer on specification by system analyst. C)Operator- is a person who operates the computer system.
