Pixel
They're called - pixels. The word pixel is a contraction of the phrase 'picture element'.
A "pixel" is simply a dot. The computer sends a signal to the monitor, causing a bunch of dots to do their thing and when they all come together it makes an image. As the dots become small enough our eyes can't distinguish the difference between dots and a picture.
The three colors in a pixel triad are red, green, and blue. By varying the intensity of each color component, millions of different colors can be represented on a screen.
The tiny dots in a satellite image are called pixels. Each pixel represents a specific color or brightness level and together they form the image that we see.
The dot pitch for a display unit is the distance between individual dots - which may be circular or in the form of an elongated circle (like a running track). Most display units, nowadays, are based on dots of three colours: red, green and blue. A pixel is unit formed by each set of three colours, and a pixel pitch is a measure based on the size of the pixel and the distance between dots of the same colour in adjacent pixels.
