Which term is used to describe graphics represented by pixels arranged in a grid?

• A. Vector
• B. Gradient
• C. Bitmap
• D. Icon

Answer: (C)

Graphics that are represented by pixels arranged in a grid are bitmaps, also called raster images. In a bitmap, each pixel holds color information, so the image’s detail depends on its resolution. When you enlarge a bitmap, you magnify those individual pixels, which can look blocky or blurry. This is different from vector graphics, which use scalable mathematical paths and stay sharp at any size. A gradient describes a smooth color transition, not how the image is stored. An icon is simply a small image and could be either bitmap or vector, but the term here refers to the storage method, which is bitmap.
