vector graphics

  
Computer graphics (such as drawings, but not pictures) that, unlike raster graphics, 
are represented as geometric shapes by mathematical equations. 

Vector graphics are generated by illustration software such as Adobe Illustrator or 
Quark'Xpress can be scaled, rotated, moved, or otherwise manipulated to any degree
 without any loss of quality, and display or print at whatever resolution is available on a monitor or printer. 
Also called object based graphics or object oriented graphics.
