It could be a hangman's noose, a bowline, a bowline on a bight, a double bowline, an overhand bight, or any number of other knots.
The bowline is the life saving knot that can be tied both one and two handed.
The bowline is used to attach a rope to a sale to hold it in place. The beauty of the bowline is that it is easy to undo after huge loads have been on it, it easy to tie, and it does not slip. When you're out in a storm at night, you want a knot that you can tie blindfolded, and also undo for that matter. It is also useful for making a loop that will not pull tight.

A Bowline on the Bight is a knot tied in the middle of a line, instead of at the end of a line, that resembles a bowline, but is not a true bowline. This is made by grasping the line so it is doubled, pulling the loop portion down - let it hang, then grasp the doubled linewith your right hand, palm facing away, and twist your hand to palm facing, forming a loop, similar to the first loop formed for a typical bowline; - next, bring the hanging doubled end up through the loop just made, just short distance, which now creates a hanging doubled loop; - open the end loop that was pulled through and pass it up, over, and down around the large loop, pulling it up to the upper hanging portion above the first loop; - pull tight, and you have a Bowline on the Bight
a single bowline on a bight is used when the bitter end of a line (rope for non-sailors) isn't availible. It, in essence alows one to put a temporary eye in a line without the bitter end.
I think bowline knots are to use up excess rope. They effectively shorten the rope to save the need for cutting down the length. That's a Sheepshank. A2. A double bowline creates two loops which do not tighten under load. One use, is as a makeshift lifting harness. Put a let through each loop and hang onto the line, for lifting a person.
Often with dingbats the placement of the words is the key to solving, so it's tougher when they are listed one after the other in question form. I can tell you that Staffordshire, reef, bowline and hitch are four types of knots.
The two most crucial knots to learn in rigging are the clove hitch and bowline.
Different knots for different occasions! The one i use most is the bowline, which is a loop.
