Answer 2

The pixel (a word invented from "picture element") is the basic unit of programmable color on a computer display or in a computer image. Think of it as a logical - rather than a physical - unit. The physical size of a pixeldepends on how you've set the resolution for the display screen.


A px (pixel) is the smallest portion of an image or display that a computer is capable of printing or displaying. You can get a better understanding of what a pixel is when zooming into an image as seen in the example to the right. pixels a monitor can show: VGA monitors display 640 x 480 (307,200) pixels per inch (PPI), SVGA monitors display 1,073 x 768 (786,432) PPI, and newer monitors can display 1,000 x 1,000 (one million) or more PPI. The number of colors that a monitor can display, however, depends on how much memory is assigned to each pixel. Two-bit memory pixels can show eight colors whereas eight-bit pixels can show 256.
