A comet's orbit can vary in shape from elliptical to highly elongated, sometimes resembling a long, narrow ellipse. This is because comets often have highly eccentric orbits that bring them close to the sun and then far out into the solar system.
Halley's Comet travels in a very long, narrow ellipse.

A comets orbit is considered a cycle because a comet circles back in an elliptical orbit.

It is called an orbit. A comet has an eccentric or parabolic orbit.
A comet that's bound to the sun and appears periodically is in an elliptical orbit. A comet that whizzes through the solar system only once and then leaves for good is in a hyperbolic orbit. If the comet is periodic but with an exceptionally long period ... thousands of years e.g. ... then we can't tell, from the small part of its orbit that we can see, whether it's elliptical or hyperbolic.
No, Halley's comet orbits the sun and its orbit is not the same each time it passes by Earth. The orbit of Halley's comet is an elliptical shape, so its distance from Earth and speed can vary during each approach.
Comets' orbits are elliptical, like all orbiting bodies.
