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

JPEG is a lossy compression technique because some of the details in the image are lost when it is compressed. This negatively affects the quality of camera pictures because they have slightly worse quality.

3. 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.

The binary sequence 01000001 could represent the letter A, the decimal number 65, or the color pink.
