Data compression basics in Intro to Computing - Flowchart & Logic Diagram

Process Overview

Data compression is the process of making data smaller so it takes up less space. This flowchart shows how data is checked and compressed step-by-step.

This flowchart shows the steps of data compression: starting with reading data, checking if it can be compressed, applying compression if yes, and storing the compressed data.

Step-by-Step Trace - 4 Steps

Step 1: Read original data to be compressed.

Step 2: Check if data is compressible.

Step 3: Apply compression algorithm.

Step 4: Store the compressed data.

This diagram shows how repeated parts of the original data are replaced by a shorter code in the compressed data.

Flowchart Quiz - 3 Questions

What is the first step in data compression?

A Read the original data

B Store compressed data

C Apply compression

D Check if data is encrypted

Key Result

Data compression reduces data size by finding patterns and replacing them with shorter codes.
