🧠 Explanation:
The unit shown on the computer monitor is called a **pixel**. Pixels are the tiny dots that make up the images and text displayed on the screen. Each pixel emits light of different colors and intensities, combining to form clear pictures and readable content. The resolution of a monitor depends on the number of pixels it can display, affecting the sharpness and clarity of the image. Understanding pixels is important for tasks like graphic design, video editing, and general computer use, as it influences the quality of visual output on screens.
