"Full HD" (with/without space) is a well-known term in video tech and usually refers to frame dimensions of 1920x1080 pixels, 16:9 format, thus 1:1 pixel ratio. 1080p refers to vertical frame size, the p means progressive and signals that a single frame contains a full image.
Full HD is also a marketing term, so footage with frame sizes beyond Full HD needed new names for differentiation. Such as GoPro with their 2.7K which actually is 1580p or so. 4K, and larger K's are now popping up everywhere in order to refer to frame sizes beyond Full HD.
