Great explanation but you may want to correct the initial description of pixels. You have 8×8=16 when in fact the correct answer is 64. Might confuse someone.

LD = 240p (288p), and any other resolutions lower than 480i
SD = 480i (576p)
ED = 480p (576i)
HD = 720p and 1080i
FHD = 1080p
UHD = 4k and 8k

Parentheses indicate PAL standards that differ from NTSC standards.

Messed up my first comment. Correction:

LD = 240p (288p), and any other resolutions lower than 480i
SD = 480i (576i)
ED = 480p (576p)
HD = 720p and 1080i
FHD = 1080p
UHD = 4k and 8k

Parentheses indicate PAL standards that differ from NTSC standards.

A technical point: Resolution is an inherently linear concept, basically how close together two tiny dots can be and still be distinguished, or how many parallel alternating black and white lines can be squeezed together without looking like a gray mass. The latter is now video resolution is actually measured. As a result, resolution is a function not of the total number of pixels but the square root, or in more practical terms the number of vertical pixels or horizontal pixels. (Well, that plus optics, compression, and so on.)

You simply forget the other very important standard 1440p or QHD also named WQHD
this is being described as Quad HD or sometimes being called the original WQXGA.

for reference 1080p is HD which is called UXGA

However almost everybody uses only the initial part of the original designation assigned to the standards
