Images or videos are made up of pixels. Each pixel is made of the triads, triads’ means group of three. Triad means the three sub pixels Red, Green, and Blue. RGB are the primary colors called Red, Green, and Blue.

What those numbers means

Pixels are the little dots that make up the image, display its color. Resolution is the total number of pixels in a video or image.
As the number of pixels increases the resolution increases. Better resolution means, more detailed and clear video, it seems good to the eyes.
Mostly resolution is called and written by the vertical resolution number. 1080, 720, 480, and 360 are showing the vertical resolution. But there is horizontal pixel count as shown below.

1. 352 x 240 (240p)
2. 480 x 360 (360p)
3. 858 x 480 (480p)

5. 1920 x 1080 (1080p)
6. 3860 x 2160 (2160p, or 4K)
