MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Resolution is measured in pixels-per-inch or PPI. The more pixels an image starts with, the higher the resolution. Decreasing the number of pixels is called downsampling, which removes data from your image.

Detailed explanation-2: -Higher resolutions mean that there more pixels per inch (PPI), resulting in more pixel information and creating a high-quality, crisp image. Images with lower resolutions have fewer pixels, and if those few pixels are too large (usually when an image is stretched), they can become visible like the image below.

Detailed explanation-3: -More number of pixels makes a better resolution of an image.

Detailed explanation-4: -Pixels per inch (PPI) refers to the number of pixels contained within each inch of a digital image. It also refers to the set number of pixels a screen can display. Generally speaking, the higher the PPI, the better the image quality. Lower resolution images contain larger pixels in fewer numbers.

Detailed explanation-5: -The pixel dimensions are always affected. Changing the pixel dimensions affects the physical size but not the resolution. Changing the resolution affects the pixel dimensions but not the physical size. Changing the physical size affects the pixel dimensions but not the resolution.
