FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Raster images are often used for digital photographs, but they can also be used for illustrations, logos, and any other type of image. Raster images are made up of pixels, which are tiny dots of colour. When you zoom in on a raster image, you can see the individual pixels that make up the image.

Detailed explanation-2: -Raster files are images built from pixels-tiny color squares that, in great quantity, can form highly detailed images such as photographs. The more pixels an image has, the higher quality it will be, and vice versa.

Detailed explanation-3: -Raster images are best for digital photos and print materials. If your project requires scalable shapes and solid colors, vector is the best choice, but if your project requires complex color blends, raster is the preferred format.

Detailed explanation-4: -Digital photographs are usually raster files. Many digital cameras automatically shoot and save photos as raster files-and the images you see online are often rasters, too. Raster files are also commonly used for editing images, photos, and graphics.

Detailed explanation-5: -The major use of raster data involves storing map information as digital images, in which the cell values relate to the pixel colours of the image. To reproduce the image the computer reads each of these cell values one by one and applies them to the pixels on the screen.
