It depends on the subject matter and end use for the art. The main reason to choose vector over raster is quality of enlargement. Rasterized art is resolution dependent and characterized by 'bitmapping' whereas vector art is created by a mathematical formula. Example: A photograph in the digital environment is rasterized, and will loose quality as it is enlarged. A logo design is best done as vector art.

raster
It all depends on the project. Raster images are resolution dependent, you loose quality if you enlarge the image. Vector graphics maintain image quality when enlarged and are best suited for logos, or any design that will be reproduced in different sizes.
Illustrator is a vector based program that can export raster images.
raster image = monitor, laser printer or ink-jet printer vector image = graphics plotter
Raster and Vector
Vector does not lose quality when resized, which is ideal for logos.
Vector and Raster or pixel images.
Yes, partially. PDF encodes fonts and EPS graphics that are vector based. It also encodes images, in JPG format for example, which are raster based.
Three types of images are raster images, vector images, and vectorized raster images. Raster images are made up of pixels, while vector images are made up of paths and can be scaled without losing quality. Vectorized raster images are raster images that have been converted into vectors, combining the best of both worlds.
You have to use programs which support vector graphics and raster graphics, so you can save them in what format you would like? ex: Adobe Illustrator, CorelDraw you can use...
