Which type of graphics are resolution independent, preferred when scaling up or down?

• A. Raster Images
• B. Vector Graphics
• C. .GIF
• D. Binary Code (1s and 0s)

Answer: (B)

Vector graphics are defined by mathematical paths and shapes, so they can be scaled to any size without losing sharpness. When you resize a vector, the program recalculates the coordinates of lines and curves, not pixels, so edges stay crisp whether you’re making a logo large for a banner or tiny for a button. That makes them ideal for scaling up or down.

In contrast, raster images are made of pixels. Scaling them up stretches those pixels, which causes blur or jagged edges, and they don’t maintain quality at different resolutions. GIF is a raster format with limited color depth, so it inherits those same scaling limitations. Binary code is just the data representation underlying digital information, not a type of graphic designed for scalable visuals.
