Which of the following is the smallest component of a screen image, composed of individual Red, Green, and Blue primary colors?

The smallest component of a screen image is known as a pixel. Pixels serve as the building blocks of digital images, with each pixel typically composed of three sub-pixels that represent the primary colors: Red, Green, and Blue (RGB). By varying the intensity of these colors, a pixel can display a vast range of colors, which together create the full image seen on the screen.

The term "pixel" is derived from "picture element," and it is specifically designed to encapsulate the visual information of images in digital formats. Each pixel in a display can be individually controlled, allowing for detailed images with smooth gradients of color when combined with many other pixels.

In contrast, a dot refers to a single point in a graphical representation but does not imply the color composition that a pixel does. A bit is the most basic unit of data in computing and represents a 0 or 1; it does not directly correspond to the visual components of an image. The term color is quite broad and does not specifically point to the smallest image element. Thus, understanding that a pixel is the fundamental unit that integrates color to form images is crucial in the context of digital displays.
