What does pixel mean?
Pixels can be regarded as indivisible units or elements in the whole image. Indivisible means that it cannot be divided into smaller units or elements. It exists in a single color cell. Each dot matrix image contains a certain number of pixels, which determine the size of the image on the screen.

Pixel position
A raster image is just a grid containing many individual pixels, and each pixel has a definable horizontal and vertical position in the grid.
In most major image editing programs, the coordinate position of any pixel can be obtained by moving a tool called eyedropper on the map. The physical size of the grid is determined by the total number of pixels and the resolution, which in turn determines the relative position of each pixel.
