A pixel is a tiny dot on a computer screen or a digital image. When you are looking at a digital image, whether it be a photograph or a graphic, it is made up of these small dots. The more pixels that are in an image, the clearer and sharper it will appear. When discussing screen resolution, you may hear terms like "pixels per inch" or "pixel density", which refer to how many of these dots are packed into a certain area on a screen. Pixels are also used in digital design and art, where the artist may create an image by piecing together a collection of smaller pixels to form a cohesive picture. So, to simplify, a pixel is a tiny dot that makes up digital images on screens and can affect how clear or sharp an image appears.
