What a pixel actually is
If you want the basics: A pixel is short for “picture element” — the smallest visible unit of a digital image. Each pixel is a tiny square with a specific color, and thousands or millions of them combine to form the full picture you see on screens. Resolution depends on how many pixels you have, and pixel density (PPI) determines sharpness.
The term goes back to 1839 with early photography, but the modern RGB version we use — mixing red, green, and blue light — was first demonstrated in 1861.

3. Pixel in tech/cybersecurity
Scientific American ran a piece on how malicious images and pixel manipulation can threaten AI agents. Researchers found images like wallpapers can hide messages invisible to humans but capable of controlling AI agents that click buttons and fill forms.
