MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -raster graphics, also called bitmap graphics, a type of digital image that uses tiny rectangular pixels, or picture elements, arranged in a grid formation to represent an image.

Detailed explanation-2: -Raster images in general may be referred to as bitmaps or pixmaps, whether synthetic or photographic, in files or memory.

Detailed explanation-4: -Bitmap-based images are comprised of pixels in a grid. Each pixel or “bit” in the image contains information about the color to be displayed. Bitmap images offer a fixed resolution and cannot be resized without losing image quality. These images are also called raster images.
