Data Processing Cycle (Video Notes)

Vocabulary flashcards covering data, information, and the data processing cycle concepts from the video notes.

Data

Raw facts or figures that have no meaning until processed.

Information

Processed data that is organized and presented to be meaningful and relevant.

Data Processing Cycle

A five-stage sequence—collection, preparation, input, processing, and output—that turns raw data into information.

Collection

The first stage of the cycle where data is gathered; the data collected is called raw data.

Preparation

The second stage where data is prepared for use by checking quality, ensuring correct units, and including necessary time periods.

Input

The stage where data is entered into the computer so software can process it.

Processing

The stage in which data is transformed through steps (such as sorting and arranging) to produce information.

Output

The stage where the processed information is displayed or returned to the user (e.g., graphs, audio, documents).

Raw data

Data that has been collected but not yet processed; examples include numbers, days, and measurements.

GIGO

Garbage In, Garbage Out — poor-quality input leads to poor-quality output.

Unit

A unit of measurement used for data values (e.g., Degree Celsius) to ensure consistency.

Temperature data example

An example of input data such as 35°C, 34°C, 33°C, 32°C, 36°C on corresponding days (Mon–Fri) used to illustrate the cycle.
