Describe what it means to say that JPEG is a lossy compression technique and whether or not it affects the quality of camera pictures.

Lossy compression means that some of the data is lost and can't be recovered. Usually this data is not visible to the eye so it doesn't affect the quality of camera pictures

Give a specific example of a binary sequence that can represent more than one type of data -- e.g., a number, a color, a character -- and describe how to interpret its different values.

One example would be the number 11111111. This can represent many things like the color white (255), or a character y.
