Pixel
Imagine trying to find a single pair of socks in a messy, overstuffed drawer. Just like how you have to reach for and identify one specific pair of socks among many, a pixel is the smallest identifiable part of a display that can be individually controlled and changed to create an image. The drawer is analogous to the entire display screen, filled with countless items (socks), and each sock represents a pixel, which is the smallest element that can be controlled to create a larger, coherent picture.
