The parts of the extruder that get hot enough to melt plastic, or potentially other materials. As opposed the cold end, which is generally made from printed thermoplastic that needs to stay cool or it will melt / deform. Hot end parts use materials that can stand up to ~240 C heat (for current thermoplastic extrusion). The hot end usually refers to the tip of the extruder as it should be hottest there.
For a list of comparing hotends see Hot End Comparison.
For general theory useful for people creating improved hot ends, see Hot End Design Theory.
