General
Manual strangulation (called throttling in the UK) refers to strangling with the hands, fingers, or other extremities (sometimes also with blunt objects such as batons). In violence, this type of strangling is mostly done by men against women rather than against another man, because it generally requires a large disparity in physical strength between the assailant and the victim and also because men can be over twice as big as a woman in general. More technical variants of manual strangulation are referred to as chokeholds, and are extensively practised and used in various martial arts, combat sports, self-defense systems, and in military hand-to-hand combat application.
It is a mistake to refer to strangulation as "choke" or "choking". Choke means having the windpipe blocked entirely or partly by some foreign object like food.

Manual strangulation
Ligature strangulation refers to strangling with some form of cord or cloth such as rope, wire, or shoe laces, either partially or fully circumferencing the neck.
