Simple description of the techniques used within each file for compression and data storage, including:

• 24-bit bitmap and compressed bitmap (RLE)

Run Length Encoding (RLE) is a lossless compression technique that works well on simple images or repetitive data.

Well the benefits of youtube in class become clear 🙂

Run-length encoding (RLE) is a very simple form of data compression in which runs of data (that is, sequences in which the same data value occurs in many consecutive data elements) are stored as a single data value and count, rather than as the original run. This is most useful on data that contains many such runs: for example, simple graphic images such as icons, line drawings, and animations. It is not useful with files that don’t have many runs as it could greatly increase the file size.
