Software used to create vector graphics is sometimes referred to as object-based editing software. Common vector formats include AI (Adobe Illustrator), CDR (CorelDRAW), CGM (Computer Graphics Metafile), SWF (Shockwave Flash), and DXF (AutoCAD and other CAD software). Vector graphics tend to have much smaller file sizes than raster-based bitmaps.
The edges of vector images are always crisp and sharp at any scale. This is why vector images are called resolution independent.
