Bitmap and Vector Images

1. A bitmap image is an image made up of various individual pixels of different colors, all put together. For example, everything on the computer screen right now is made up of pixels, so it is essentially a bitmap.

2. Resolution-dependent means that the quality and size of the image depend on how many pixels are in every inch of your monitor. The more pixels per inch, the better the image will look.

3. A vector image relies on mathematical equations to determine how all the lines will appear on the screen, instead of individual pixels being put together.

4. It's easy to notice a difference because bitmap images don't scale very well, since all you're doing is increasing the size of the pixels. However, since vector images rely on equations, the image probably knows it's growing and will adjust the equation accordingly, to keep the quality good. Also, in general, vector images look sharper and more "cartoony" for lack of a better word.
