The document outlines the basic data processing cycle which involves 4 key operations - input, process, storage, and output. Data is entered through input devices, manipulated and processed by the processor, stored on storage devices like hard disks, and finally output through output devices to present the useful information to the user.

1. DATA
PROCESSING
CYCLE

2. The computer system processes
data into information through four
operations:
1. input
2. process
3. storage
4. output.

4. INPUT
The user enters the data by using
an input device (such as
keyboard, mouse) electronically
and is processed by the
processor.

5. PROCESS
Data is manipulated to process or
transform it into information in the
processing operation.

6. STORAGE
The storage (such as hard disk,
compact disc (CD), diskettes)
holds data, information and
programs.

7. OUTPUT
The output devices (such as
monitor, printer) present the
processed data as useful
information products to the user.
