Bitmapped graphics and Vector graphics
Advantages and Disadvantages of using bit mapped graphic representation
typically do not scale very well. Shrinking an image by decimation (throwing away pixels) can change the image in an unacceptable manner, as can expanding the image through pixel replication. Because of this, bitmap files must usually be printed at the resolution in which they were originally stored.
Bitmap files may translate well to dot-format output devices such as printers.
Bitmap files may be easily created from existing pixel data stored in an array in memory.
Pixel values may be modified individually or as large groups by altering a palette if present.
how bit mapped graphics are represented
Bitmaps are also known as pixelmaps or raster graphics. Bitmap images are organised as a grid of coloured squares called pixels (short for 'picture elements'). When zooming in or enlarging a bitmap image, the pixels are stretched and made into larger blocks. ... Each colour of an image is stored as a binary number.

How vector graphics are represented
Vector graphics is the use of polygons to represent images in computer graphics. Vector graphics are based on vectors, which lead through locations called control points or nodes. ... Vector-based images are not made up of a specific number of dots, they can be scaled to a larger size and not lose any image quality.
Advantages and Disadvantages of using Vector graphic
They don't lose quality when you scale them
Vector images usually require less disk space as compared to bitmap. They are formed mostly by simple gradients or flat colors since they don't require too much disk space.
One more disadvantage is that even the smallest of errors in the drawings are visible when you enlarge images to an extent. These incidents can affect image quality, especially when used in animation.
They aren’t too suitable for encoding videos or pictures from the real world.
