Pixel
In English pixel, the abbreviation of image elements (picture element) is the number of points in the unit area that make up the image. Each pixel has a different color value. The more pixels in the unit area, the higher the resolution, the better the effect of the image. Pixels are sometimes referred to as PEL
principle of Google, find some answers on the internet, the following is a simple answer. 1. DPI and PPI what the hell.
The DPI (Dots per Inch) is initially used to measure the number of points that are printed without an inch, which means that your printer can hit as many points in an inch. The smaller the DPI value, the less pleasant the picture is.
When the concept of the DPI is used on a computer screen, it should be called PPI (Pixels per Inch)
