What does 1080p mean in laptop resolution?

What does 1080p mean in laptop resolution? Dell is selling a laptop (Studio 15) where the options for screen resolution are 720p, 900p, and 1080p. What do they mean?

"720p is 1366x768

HD (High Definition) - approx 16:9
(HDTV is 1280x720, yet both were marketed as 720p instead of laptop's 768p, films are actually 768p and yet your HDTV can still visualise them)

900p is 1600x900

HD+ (High Definition Plus) - 16:9

1080p is 1920x1080

FulHD (Full High Definition) - 16:9

4K is 4096x2160

4K (The current standard, as of 2012, in digital cinema) - 1.8962:1

2880p is 5120x2880

5K (Retina 5K Display) - 16:9

8K UHD is 7680x4320

8K (Ultra-high-definition/Super Hi-Vision) - 16:9"

Some caveats to the above: HD video is shot (and played back) at 1920x1080 resolution. Most digital "film" shoots (using professional cameras such as the RED or ARRI) are done at 2K resolution, meaning 2048x1080p. Few higher-end digital cameras are limited to 1920x1080 resolution, so image editing could be tricky. Also, be aware that a screen with only 1920x1080 pixels has no extra room for borders, video controls, toolbars, skins, etc. To see anything at full resolution, it must be displayed in "full screen" mode only. So I would NEVER buy a computer display with only 1080 vertical pixels or only 1920 horizontal pixels.
