Question

write a short note on pixel​

Answer 1

Explanation:

Pictures are made up of pixels which are small dots or points of information. A high definition image is created from a large amount of pixels, while a low definition image is created with fewer pixels. A px (pixel) is the smallest portion of an image or display that a computer is capable of printing or displaying. As you can see in this example, the character image in this picture is zoomed into at 1600%. Each of the blocks seen in the example picture is a single pixel of this image.A pixel contains the digital numeric RGB color data (numbers) of one tiny surface area. It creates a row and column array of pixels, perhaps of size 4288*2848 pixels (12 megapixels).
