vector is a type of digital image built from shapes instead of pixels, which can be scaled indefinitely and modified without loss of quality. They look like this. You can find a more detailed description on Wikipedia. What does it look like to create a vector? How can vector files be used? Only a few programs can create vectors! Examples of proper vector programs are Inkscape (free, most recommended), Illustrator (also recommended), and Photoshop (not recommended), while programs which CANNOT make vectors are, for example, GIMP and Paint.NET.
