What does the term "pixel" refer to?

The term "pixel" stands for "picture element," which is the fundamental unit of a digital image or display. Each pixel represents a single point in the image, and collectively, a grid of pixels forms the complete visual representation. This concept is essential in understanding how images are displayed on screens and processed by computers.

In digital displays, each pixel can vary in color and brightness depending on the display technology used, contributing to the overall image quality. High-resolution images have more pixels packed into the same area, resulting in finer detail and sharper images. Understanding what a pixel is and its role in image representation helps in fields such as graphic design, web development, and photography.

The other choices relate to aspects of digital imaging but do not define what a pixel is. Image resolution refers to the total number of pixels in an image, often expressed in dimensions like width and height (e.g., 1920x1080). Print quality is influenced by several factors, including resolution and the printer's ability to reproduce color accurately but does not directly define a pixel. Color depth pertains to the number of bits used to represent the color of each pixel, affecting the number of colors a pixel can display, but again, this is not the definition of a pixel itself
