Data Compression

Data can be reduced in size to save space this is called compression.
You can use software like Zip software to do this for you but the principle is the same.

For example compression can be achieved  by converting and reducing text to prevent repeated words.

So for example:
Pitter Patter
Pitter Patter
Listen to the Rain
Pitter Patter
Pitter Patter
On the Window Pain.

Becomes:

Pit Pat
Listen to the rain
On window pain.
