Which term describes smooth drawings made up of lines and curves?

The term that describes smooth drawings made up of lines and curves is vector graphics. Vector graphics are defined using mathematical equations and geometric primitives such as points, lines, and curves. This allows for scalability without any loss of quality, meaning that these images can be resized to any dimension while maintaining their smooth edges and overall clarity.

Unlike bitmap images or raster images, which are composed of pixels and can become pixelated when enlarged, vector graphics retain their sharpness at any size. This makes them particularly suitable for designs that require precision and scalability, such as logos, icons, and illustrations. Using vector graphics is essential in graphic design because they offer flexibility and adaptability for various applications in printing and digital media. This characteristic distinctly separates them from the other options, emphasizing why vector graphics is the correct choice for this question.
