Vector is a term used in a graphic design. Its original context is SVG which stands for Scalable Vector Graphics. Scalable means even if you try to resize it, be it smaller or larger, the quality of the image or the pixels, will not be affected or deteriorated. It will still be the same, compared to Bitmap, that when you resize it, the quality is subjected to change resulting to blurry image. Vector is applicable to Logo designs and the like because if in case you needed to resize them for future use, you are completely able to do so. The quality will remain intact. The drawback in using vector is that it is not as fine as bitmap images or photographs do. Because vectors contain selectable regions only, meaning it is limited. In vector, the other detail such as fineness or color is not enriched or vivid compared to bitmap. Though you can manually achieve it, it will require you to go on pixel by pixel editing.
