MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Pixels per inch (PPI) is the measure of resolution in a digital image or video display. Pixels per inch (PPI) is typically used to refer to the display resolution, or pixel density, of a computer monitor or screen. The greater the pixels per inch (PPI), the greater the detail in the image or display.

Detailed explanation-2: -It is a measure of the resolution of a printed document or digital scan. It measures how many dots fit into a linear inch. The higher the dot density, the higher the resolution of the print or scan. A printer with 600 DPI is a printer that prints 600 x 600 per square inch or 360, 000 dots per inch.

Detailed explanation-3: -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-4: -DPI refers to the number of printed dots contained within one inch of an image printed by a printer. PPI refers to the number of pixels contained within one inch of an image displayed on a computer monitor.

Detailed explanation-5: -PPI stands for ‘Pixels Per Inch’ and DPI for ‘Dots Per Inch’ ‘ so a pixel is not a dot. Pixels relate to digital images as seen on your monitor and captured in your camera. Dots relate to the droplets of ink your printer spits out of the print head and its ability to print those images in detail.
