Week 2 - Abstraction layers

In week 2 we will be looking at the idea of layers of abstraction. To illustrate the benefits of abstraction, we will spend some time looking at the physical layer and how to delve into it by looking at the Exif data in JPEG files.

• The Powerpoint Slides
• An ASCII table
• A simple Hex editor
• Sample JPEG and MP3 files

In the workshop you will use the hex editor to explore other JPEG files and to unpick MP3 ID3 metadata. Progress on the Flickr review will also be checked.
