Introduction to Data Processing
Data Processing is the process of producing meaningful information from raw data. It describes the series of actions taken to produce useful information by collecting all items of data together and performing operations on them. Data processing aims to convert raw data into information.
Data: Data represent the raw unprocessed input element introduced into a system from which useful information is extracted. Data is used to describe the facts and figure obtained which have not been grouped, related or evaluated in any way.
Information: Information consists of data which have been recorded organized classified and processed into a useful and meaningful form. It is the output element of a data processing system.
Qualities of good information

- Electronic Data Processing
- Differentiate between data and information.
- List five qualities of good information.
The electronic computer
Characteristics of a Computer
- Speed – high speed of operation
- Storage – Large storage volume
- Versatility – Can be used to perform a wide range of tasks
- Diligence – It can perform similar operations at the same speed and accuracy at all times.
- Automatic – Tasks are performed automatically based on the programme (instructions) given to the computer.
Components of a computer
- Input devices – i. .e. the unit through which data are fed into the computer e.g. keyboards, terminals, optical mark readers optical character readers, magnetic ink character readers.
- Central processing unit – This is the part of the computer that carry out the computations and calculations. It is made up of
(a) The control unit
(b) The Arithmetic and Logic Unit
(c) The Internal Memory or Storage
- Output devices – These are used to transmit processed data to the users e.g. printer, visual display units, plotters.
- Storage devices – These are external storage devices used to hold information that would be required by the users of the computer e.g. diskettes, magnetic tapes, punched cards etc.
