Quad Core? LTE? Retina Display? In laymen's terms please...

can explain these buzz words mean?

 

i know 4g , quad core mean better , faster, can explain retina display:

if @ computer screen, see pixels. on retina display, pixels small , close it's difficult (if not impossible) see individual pixels when hold product @ normal length.

it's difference between old tvs , flatscreen ones. can see image on both, when @ 1 of older ones (especially after using flatscreen while) see less clear image , can see little dots used make image.
