Representing Data
You will be responsible for understanding the core concepts behind all the formats/file types (listed in chapter 3 of the book for representing for various types of data (text, images, video), the pros and cons of different formats and when it is appropriate to use different formats. For instance, jpg’s are meant to realistically represent photographs and use color averaging, while GIF’s have a max of 256 colors and therefore have much smaller file sizes than jpegs ; the latter are not a good choice for representing photographs but rather for cartoons or line art. Both of these are Raster not vector shapes.
