    DefinitionPixel, an abbreviation of Picture Element, is the smallest controllable element of a picture represented on a screen.
    FunctionEach pixel stores color information for an image and collectively forms the complete image.
    CompositionA pixel is typically composed of red, green, and blue sub-pixels. The combination of these defines the pixel’s color.
    ResolutionThe number of pixels in an image or a screen defines its resolution. Higher pixel count means higher resolution and more detailed image quality.
    Pixel DensityIt is measured in pixels per inch (PPI). It indicates the display quality. Higher PPI means a clearer and less pixelated image.
    Pixel Bit DepthIt refers to the color information stored in each pixel. A higher bit depth allows for a greater range of colors.
    Pixels in Digital PhotographyIn digital photography, pixels are used to capture and represent the digital image. The photo’s quality and clarity are proportional to its pixel count.
    Pixel ArtIt’s a style of digital art where images are created using tiny, square-shaped pixels. It harks back to the early days of computer graphics.
