Define data processing
State the stages of data processing
Describe what each stage entails

3. DATA
• Facts, observations, assumptions or occurrences
• Facts representing people, things, ideas and events
• Are represented by symbols such as letters of the alphabets,
numerals or special symbols.

4. WHAT IS DATA PROCESSING?
• Data processing is a series of operations performed especially
by a computer on data to transform, classify and retrieve
information.
• It can also be defined as a series of operations that are carried
out on data, especially by computers, in order to present,
interpret or retrieve information.

5. DATA PROCESSING STAGES
• Data gathering stage
• Data collation stage
• Input stage
• Processing stage
• Storage
• Output stage

6. DATA GATHERING STAGE
• Involves collecting data in its raw form

7. DATA COLLATION STAGE
• Involves assembling data in its proper numerical or logical
sequence.

8. INPUT STAGE
It is the stage where data are entered into the computer through
the keyboard, the mouse, the scanner or digitizer.

9. PROCESSING STAGE
• Data are manipulated and transformed into a desirable form.

10. STORAGE STAGE
• It is a stage in the processing cycle whereby data instructions
and information are held for future use.

11. OUTPUT STAGE
• It is the stage where processed information is transmitted to
the user.
