It's always important to remember the difference between raster and vector, as well as, screen resolution (72 dpi) and print resolution (300 dpi).
A raster is an image made of hundreds (or thousands or millions) of pixels. When enlarging a raster file it will become blurry. Popular raster extensions include: jpg/jpeg, psd, png, tiff, bmp, and gif.
A vector image uses math to draw shapes using points, lines and curves. So whereas a raster image of a 1” x 1” square at 300 dpi will have 300 individuals pieces of information, a vector image will only contain four points, one for each corner; the computer will use math to “connect the dots” and fill in all of the missing information. Meaning a vector image is infinitely scalable. Most common vector extensions are: eps, ai, and pdf.
Now to make it easy to understand the difference between screen resolution (72 dpi) and print resolution (300 dpi), don't ever pull an image off of a computer screen and think it will print well. You must have a high-resolution source file. If you're not sure, ask your commercial printer.
