How is a bitmap image defined?

A bitmap image is defined as an image that is created by colored dots on a grid. This description captures the essence of how bitmap images work: they are composed of a grid of pixels, with each pixel representing a specific color. This grid structure allows for the representation of intricate details and color variations in an image. When you zoom in on a bitmap, you can see these individual pixels, showcasing the way the image is formed through the arrangement of these colored dots.

The term "bitmap" itself reflects this concept, originating from the combination of "bit" (the basic unit of information in computing) and "map," which refers to the arrangement of those bits in a spatial form. Consequently, when referring to bitmap images, it is crucial to note that they can include a wide range of colors, leading to rich and complex images.

In contrast, other options refer to different types of image constructions. Shapes and paths are characteristics of vector images, while image representations based on mathematical equations pertain to vector graphics as well. Lastly, the claim of an image only displaying in black and white would not accurately describe bitmap images, as they can display a full spectrum of colors.
