MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Raster (or bitmap) images are generally what you think about when thinking of images. These are the types of images that are produced when scanning or photographing an object. Raster images are compiled using pixels, or tiny dots, containing unique color and tonal information that come together to create the image.

Detailed explanation-2: -But, beginners sometimes get confused. Vector and bitmap (also called raster) images are two different types of digital images. Vector images are made up of lines and curves that are defined by mathematical algorithms, while bitmap images are made up of a grid of pixels.

Detailed explanation-3: -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.

Detailed explanation-4: -Raster graphics are digital images created or captured (for example, by scanning in a photo) as a set of samples of a given space. A raster is a grid of X and Y coordinates on a display space. (And for three-dimensional images, a z coordinate.)
